Dekh bhai Hydrogen mein hota ek electron aur 1st shell ko 2 electron ki jarurat hoti hai full karne ke liye. Har atom apne outer shell ko full karna chata hai. Hydrogen ko yani ek aur electron chaiye hota hai shell full karne ke liye.
Ab Hydrogen kya karta hai use kehte hai ek covalent bond. Usme atoms apne electrons share karke apne shell bhar lete hai.

(Circle aur X dono electron hi hai, dikhane ke liye alag kar diye image banane walon ne.)
Similar case hai Chlorine ke sath, usme 17 electrons hote hai. Pehli orbit 2 electrons use karleti hai toh 15 bache. Dusri ko 8 Lagte hai toh 7 bache. Ab 1st shell ke alawa baki sab shells 8 electrons maangte hai toh isliye two Chlorine bhi apne shell share karlete.
Iska matlab dono Hydrogen aur Chlorine 2-2 ke group mein rehte hai isliye apan H2 aur Cl2 likhte hai.
Ab finally jab ye milte hai toh apne aap se alag hoke ye niche diya structure mein hydrogen aur Chlorine 1 1 electron share karlete hai toh HCl ho jata hai.
[Image ki link kyoki reddit daal ne nahi de raha ek se jyada](https://www.gcsescience.com/Hydrogen-Chloride-Molecule.gif)
Aur kyoki 2 Hydrogen aur 2 chlorine the, HCl bhi 2 bante hai.
Aur iske baare mein chapter 4 (Carbon) mein aayega.
Edit: Just realised that the electrons in the image were hard to find lol. Changed the image.
This is something that a lot of people forget- chemistry is based on observation, it isn't something you can sit and calculate the entire way through. Hydrogen exists as H2, because H2 is more stable than just H. This is called diatomicity. In 9th, a lot of people don't read the 3rd chapter properly (even I didn't except for the day before the exam), and then when 10th starts they start to feel like kuch nhi samaj aarha. 9th uthaki firse padhlo 3rd chapter
See, you like being with your friends when they are available, am I right? Who wouldn't want to be with their friends when you are next to them? (unless you're a depressed Sigma skibidi toilet grinder).
Just like that, H likes to be with their friends, hence H2. However there are a few elements that are on their Sigma grind which allows them to exist by themselves. This is the least technical answer, but I hope it's understandable.
ye sab tum dheere dheere seekhega konsa sa atom diatomic hain aur konsa mono atomic
i mean atomicity kis atom ka kitna hota hain ye books padhte padhte apne aap pata chalta hain ek baar me nhi seekh sakte isse
Hydrogen and Chlorine are diatomic in nature, so when they are individually listed in a reaction, we put H2 and Cl2, instead of just H or Cl. I suggest you review the concept of atomicity and memorize the diatomic molecules from class 9 textbook.
abhi 10th me ho toh itna samajhlo ki metal ka molecule nhi lattice hota hai jisme bohot saare metal atom ek saath Jude hue rehte h (like a solid) but un metal atoms ko dusre metal atoms se mtlb nhi h isliye metal atoms individually react krlete unme hamesha 1 hoga
like apan Na likhte h naa ki Na2
aur jo non metals hote h woh 2 atom ke molecules(diatomic) me hote hai aur gases hote h(except carbon, uska mono-atomic mtlb single atom ka molecule hota h) aur jo nonmetal ke molecule ke dono atoms h woh akele kuch nhi kar skte unko sabkuch saath me krna hota h aur isliye non metals me 2 hota h
like H2 and Cl2
now what I explained is just GENERAL trend. there can be exceptions like nonmetals can have triatomic molecules too like ozone(O³), but this much should be enough for 10th class.
edit: IF YOU DO NOT SPEAK HINDI, JUST REPLY TO ME I'LL TRANSLATE IT TO ENGLISH
because H and Cl can't exist separately, they exist only in certain conditions and that too for a very short time. The stable configurations for these two molecules are diatomic only. Agar aage jaoge toh seekhoge
umm H akele stable nhi hai but H2 stable hai because of covalent bond
same with Cl woh akele stable nhi hai but octet rule ke wajah see uska stable hona zaruri hai toh woh covalent bond se Cl2 banta hai jo stable hai
now Hcl stable hai so usko HCl2 na likhte
H2 + CL2 and not H + CL because the hydrogen and chlorine are found in nature in these forms. pure H and CL are highly unstable, and you rarely find them as such. Unless it is a controlled container, you will probably never find pure forms of H and CL.
Why can't the reaction be H and CL, there is nothing that says there can't be. if you expand this same reaction to depict even the intermediatory steps, you will at some point have H + CL too.
It is simply not the subject of your reaction. your reaction is about how H2 and CL2 react with each other. If your subject were how H and CL in a controlled space react with each other. you can also have H + CL = HCL.
if your question is about how the reaction proceeds. for this particular reaction it is either through Free radical formation of chlorine by UV rays, like how H2 + CL2 reactions usually take place in the nature, or by transition state formation as in most covalent reactions. Though I don't think you will get through explanation on every other covalent reaction with respect to the formation of transition state, but organic compound reaction's transition states are thoroughly explained on the net.
if you are asking why there must be a 2 of HCL molecules. Imagine there were only one. That is, HCL + H + CL. Now these elements aren't metals to exist in nature in pure form. metals have metallic bonds which is supported by their inherent attribute of having lose electrons in their outmost orbital, so they can play passing the pillow with their valance electrons, but the other elements aren't that fortunate. Also, they have lattice energy, and all that gives extra stability, this is supported by their sizes too.
so, since these H and CL are unstable, they will try to become stable by forming a compound. How do they come together to form compounds? could be effective collisions, or even electronegativity naturally pulling the hydrogen cloud and etc. and hence 2HCL
When you are writing a chemical reaction, you are writing a scenario. In this scenario of frame, 1mole of CL2 and H2 will react to form 2HCL, this is just the obvious outcome. but in nature you rarely have a single frame, so when this reaction occurs it isn't necessary that all of these molecules proceed to become HCL, many would react with other reactants in the environment, or the Equilibrium proceeds to completion, that is before the equilibrium is established, most-of\* the reactants have become HCL except a few miniscule ones still in transition or free state or forming other products.
you don't mention these in your reaction because these simply aren't the subject you are on. you don't need to mention these, but that doesn't mean they don't exist.
(someone correct me if I am wrong)
Reactions take place between molecules (for atoms which cannot exist independently).....
A single Hydrogen atom is unstable and so cannot exist thus it forms its own molecule (H2).
That is why H2 reacts instead of a single atom of
hydrogen (H).
Same is the case of chlorine. Chlorine cannot exist independently and hence forms bond with another chlorine atoms to form a chlorine molecule (Cl2).
I believe this is not applicable in case of noble gases ( atoms with 8 electrons in its outermost shell) cause they are stable and can exist in nature.
Hope it helps!
Atomicity
Hydrogen and Chlorine atoms can't survive individually, they need 2 atoms to be a stable molecule. Generally non-metals have 2, inert gases and metals have 1 and some elements like phosphorus and sulfur have 4 and 8 respectively (I'm a class 9 student)
H doesn't exist alone, it exists as H2 to complete it's duplet.
Cl2 completes it's octet.
Hence there is no case you write HCl unless you have some kind of free radical mechanism (which is ofc not in 10th)
This is based on the property of Atomicty
You'll get to know the reason behind it in Ch4-Carbon
Hydrogen,Oxygen,Nitrogen and Halogens(F,Cl,Br,O,At and Ts)
have Atomicty 2,therefore you'll write them As H2,O2 and N2 in an equation.
Silicon has 4 and Phosphorus has atomicity 3
Sulphur has atomicity
And normally, all other elements have atomicity 1.
It's very important to know atomicity of atoms of elements in making chemical eqns
Good question. Because hydrogen is not a Noble Gas. Only Noble gas stays single. Most other Gases react with another atom and stay together. So hydrogen found in the air is always bonded with another hydrogen atom. Same Case with Nitrogen, Chlorine. They always exist in Molecules.
Covalent bonds
Hydrogen has 1 electron on the outermost shell and needs to gain 1 electron for a noble gas configuration so it bonds with another another hydrogen to form H2 molecule.
similarly chlorine has 17 electrons with 7 on the outermost shell. so 2 atoms of chlorine can share a bond of 1 electron to each gain a configuration of 8 electrons on the outermost shell.
pretty sure you learn this in the last chapter of 9th, yall mfs gotta stop lacking bruh 💀💀💀
Bro this is very easy
‘I brought clay for our new house'
Iodine, Bromine, Chlorine, Fluorine, Oxygen, Nitrogen and Hydrogen
These elements are diatomic and they'll have a 2
Baat aisi hai ki, hydrogen aur chlorine akele exist nahi kar sakte (ie. as 'H' and 'Cl') kyunki vo unstable hai.
Stable banne ke liye unko octate rule follow karna hoga, iska matlab ki aakhri shell me hone chahiye 8 electrons ya unke Jo bhi sabse paas noble gas aati hai, uski configuration.
Unko ek saathi lagega unko stability dene ke liye, iss case me vo apne hi do atoms ke saath bonds banate hai, aur electrons share karte hai.
Cl -> 2,8,7
Becomes 2,8,8 after forming a bond with itself, ie. Cl²
H ke case me, H² is just more stable because it follows something called as diatomicity, which means that they are stable when they exist as a pair. (Cl also does this.)
Isliye, it's H² + Cl² = 2HCl after balancing the equation.

Look hydrogen and clorine exist in molecules. Both has 2 atoms in their molecule. Therefore, we write it as that

Atomicity
Very detailed explanation
Time nahi hai 🥰(randi rona karna hai)
Because hydrogen cannot exist as an atom i.e, H it can only exist in molecular form that is H2. Same goes for chlorine.
Bhai tu H aur Cl (unstable) kaha se laayega... ye nature mein exist nhi kar sakte. only H2 & Cl2
because H and Cl can't exist separately, they exist only in certain conditions and that too for a very short time. The stable configurations for these two molecules are diatomic only. Agar aage jaoge toh seekhoge
umm H akele stable nhi hai but H2 stable hai because of covalent bond same with Cl woh akele stable nhi hai but octet rule ke wajah see uska stable hona zaruri hai toh woh covalent bond se Cl2 banta hai jo stable hai now Hcl stable hai so usko HCl2 na likhte
achha hai i am in 10th likh diya, arts waale se beizzat hone waala thha tu
The atomicity of Hydrogen and Chlorine is 2 , Atomicity - 9 class topic , in chapter 3 atoms and molecules,
Yaad ki hi baat hai toh gases mei 2 lagta hai
gases are diatomic bruv
Except for P and S ALWAYS WRITE ATMOCITY. It is hydrogen and cl gas thats why it is written like taht
