Question #967b6

1 Answer

valency is the major factor for formation of bonds
lets take carbon it has four valency so it can take up four bonds
valency is the no of electron in the outer shell
carbon has four electron in the outer shell
so it has incomplete octet
to complete its octet it has to form bonds with others
it forms covalent bond ie sharing of electrons between the element to whom it is bonded
it is bonded to the element or atom which need four electrons to complete its octet
