Why is there a subscript 2 for oxygen?

1. The symbol for the element oxygen, O, represents both the element and one atom of oxygen. A molecule of oxygen, O2, contains two oxygen atoms; the subscript 2 in the formula must be used to distinguish the diatomic molecule from two single oxygen atoms.

If a charge is present, it's indicated in superscript, with a sign (+/-) and a number if more than one charge is present. For example, calcium ions have two positive charges so are written Ca2+.

Why do we write hydrogen as H2?

Because there are two hydrogen atoms, we call this diatomic hydrogen, di meaning two. Because the hydrogen atoms are covalently bonded together they form a molecule; so H2 is also referred to as molecular hydrogen. We can also refer to it as dihydrogen.
