Have a look at the Lewis structure of the ammonium ion: Notice that nitrogen's octet is complete as soon it bonds with three $\ce{H}$ atoms (aka forms ammonia). Ex: Magnesium – one magnesium atom loses 2 electrons to achieve the inert gas electron configuration, therefore, the valency of magnesium is 2(or +2). Find the sum of the values in the last column. Recall that covalency is the number of shared electron pairs formed by an atom of that element. Share with your friends. Add those nine numbers together. The number of electrons lost or gained by one atom of the element to achieve the nearest inert gas electron configuration is called its electrovalency.

Nitrogen's maximum covalency is indeed $4$. Covalency . Ionic/Covalent haracter depends on size of cation(Fajan's rule) and electronegativity. A covalent bond or molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. Covalency and drawing molecules. From the figure, it can be seen that oxidation numberof S is zero (elemental form) and its co-valency is 2 as each atom is linked to two other atoms. Covalency of an element for example hydrogen, nitrogen, oxygen, fluorine is the total number of unpaired electrons in s or p orbitals. Covalency definition is - covalence.
