The Nitrogen Atom possesses seven protons in its nucleus; therefore the electrically neutral atom of Nitrogen has seven electrons in orbit about it.
6 total electrons are shared in a nitrogen molecule - 3 from each atom.
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
There are three bonds between Nitrogen and hydrogen and there are thus 3 shared bonding pairs of electrons. in addition since Nitrogen is 1s22s22p3 there are also the none bonding 1s2 electrons and the 2s2 electrons making 5 total shared pairs of electrons.

Two electrons from each element are shared; the total is four electrons.
8 O=C=O Carbon and each oxygen are bonded by a double covalent bond consisting of 4 shared electrons. 2 double bonds = 8 electrons.
In a carbon-carbon double bond, and in any other non-dative covalent double bond, four electrons are shared in total. Two are shared from each atom. In single bonds, one electron from each atom is shared, and three from each are shared in triple bonds.
In water molecules there are 2 atoms of hydrogen of and 1 atom of oxygen present. each hydrogen atom shares 1 electron with the oxygen atom. So the total number of electrons shared with oxygen are 2,total no. of electrons shared by hydrogen is 2 and the total no. of electrons shared by each hydrogen atom is 1.
