The elements with a 2 in their formula are hydrogen, nitrogen and oxygen, plus the elements in group 7 (IUPAC group 17). An element is a chemical substance made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmuted into another element through a nuclear reaction.This is so because all of the atoms in a sample of an element have the same number of protons, though they may be different isotopes, with differing.

That is, they are both composed of the same number of atoms of the same three elements, but the arrangement of those atoms in space differs between the two compounds, and this accounts for their chemical differences.
