N2 has a triple bond, since each atom will share 3 valence electrons.
Nitrogen gas is naturally diatomic, meaning each Nitrogen bond is two atoms.
————
H2 has a single bond, since each atom will share its only valence electron.
Like Nitrogen, Hydrogen is naturally diatomic.
————
O2 has a double bond, since each atom will share two valence electrons.
Like the other elements, Oxygen is naturally diatomic.
Good luck to you!
