Question

Pre-Medical : Chemistry
. Two atoms of hydrogen combine to form a molecule
of hydrogen gas, the energy of the H, molecule is :
(1) Greater than that of seperate atoms
(2) Equal to that of seperate atoms
(3) Lower than that of seperate atoms
(4) Some times lower and some times higher​

Answer 1

Explanation:

When two atoms of Hydrogen combine to form H molecule

(H2)

They will have covalent bond

There bond will be very strong..

and they'll share electrons

(3) energy will be lower

As they form bond to become stable

and we already know that

energy is inversely proportional to stability

So

(3) is correct
