|
When a metal and a non-metal bond together
|
|
|
When 2 metals bond together
|
|
|
When 2 non-metals bond together
|

|
None of the above

Explanation:
Detailed explanation-1: -Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Detailed explanation-2: -If one nonmetal has a different electronegativity than the other, the shared electrons will on average be closer to the more electronegative atom. This difference results in the bond being polar covalent.
Detailed explanation-3: -Covalent bonding occurs between two non-metallic atoms characterized by the sharing of electron pairs between the atoms and other covalent bonds with electronegativity difference is greater than 2.0 (<2.0). In the case of covalent bond formation, polyatomic ions are formed.
