Question: Distinguish between the terms electronegativity and electron affinity covalent bond
Distinguish between the terms electronegativity and electron affinity, covalent bond and ionic bond, and pure covalent bond and polar covalent bond. Characterize the types of bonds in terms of electronegativity difference. Energetically, why do ionic and covalent bonds form?
