Question

why is it not easy for carbon atoms to form positive and negative ions​

Answer 1

Answer:

Covalent Bonding

This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. ... For example: carbon does not form ionic bonds because it has 4 valence electrons, half of an octet. To form ionic bonds, Carbon molecules must either gain or lose 4 electrons.

Answer 2

Answer:

Because both atoms have the same affinity for electrons and neither has a tendency to donate them, they share electrons in order to achieve octet configuration and become more stable. ... For example: carbon does not form ionic bonds because it has 4 valence electrons, half of an octet.
