Question

Carbon forms covalent bonds. Give reason

Answer 1

Because carbon has 4 electrons in its outermost shell (and because each covalent bond requires a donation of 1 electron, per atom, to the bond) carbon has exactly four bonds to make, and is only stable if all 4 of these bonds are used. This same rule applies to all of the atoms in the second row of the periodic table.

Answer 2

they have capabilities of catenation(self linking of carbon)
