The combining capacity of the atoms to form molecules either with same or different elements is defined as valency.
Method to find valency:
If Atom has less than four electrons in its outermost shell, the valency of an atom is equal to the number of electrons present in the valence shell.
If the outer shell has more than four electrons, the valency = 8 - the number of electrons in the outer shell.
Example 1: Carbon
Electronic configuration of carbon 2, 4
Carbon has 4 electrons in its outermost shell, so the valency of Carbon is 4.
