Answer 2

Answer:

HELLO BUDDY !!!

OXYGEN :- Its known as diatomic molecule.It has atomic number as 8 , So it has its K shell completely filled with 2 electrons.While it has only 6 electrons in L shell which requires 8 electrons to get inert gas configuration....

So oxygen atom shares 2 electrons with other oxygen atom to form diatomic molecule...
