Concept explainers
a.
Interpretation: The most electronegative element in
Concept Introduction: The ability of an atom to attract the bonded electrons in a bond is said to be electronegativity. The three general categories that emerge from the electronegativity values of atoms in a bond are categorized as: covalent, polar covalent, and ionic.
