A covalent bond is the chemical bond which involves the sharing of pairs of electrons between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.
Carbon does not form ionic bonds since it has 4 valence electrons, half of an octet. To form ionic bonds, Carbon molecules must either gain or lose 4 electrons. This is highly unfavorable; therefore, Carbon molecules share their 4 valence electrons through single, double, and triple bonds so that each atom can achieve noble gas configuration
On moving down the group the metallic character increases and it gains a tendency to loose electron easiliy due to large size and easiliy formation of +2 state.
