Determine the oxidation state of nitrogen and the type of chemical bond in things HNO3, NO2, NH4NO2, Ba3N2

1) HNO3 (H (+1), N (+5), O (-2)); chemical bond – covalent polar.
2) NO2 (N (+4), O (-2)); chemical bond – covalent polar.
3) NH4NO2 (N (-3), H (+1), N (+3), O (-2)); chemical bond – donor-acceptor (a type of covalent bond).
4) Ba3N2 (Ba (+2), N (-3)); chemical bond – ionic.
