What\'s valency

1.	What\'s valency
Answer» No. Of atoms lost or gained by an atom to get its duplet or octet complete. For e.g : Oxygen has electronic configuration as : 2,6 so it has to gain 2 electrons to get its octet complete. Therefore its valency is 2.? The\xa0combining capacity\xa0of the atoms to form\xa0molecules\xa0either with same or different elements is defined as\xa0valency.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:\xa0CarbonElectronic configuration of carbon 2, 4Carbon has 4 electrons in its outermost shell, so the valency of Carbon is 4.
