Answer
The necessary conditions for the formation of covalent molecules are:
- Both atoms should have four or more electrons in their outermost shells, i.e., non-metals (exceptions are H, Be, B, Al, etc).
- Both the atoms should have high electronegativity.
- Both the atoms should have high electron affinity.
- Both the atoms should have high ionization energy.
- The electronegativity difference between the combining atoms should either be zero or negligible.
