Question

Electronegativity is the tendency of an atom in a molecule to attract the shared pair of electrons towards itself.

• A. True
• B. False

Answer 1

The correct option is A

True

Do not confuse electronegativity with electron affinity. It may be defined as the tendency of an atom to attract the shared pair of electrons of a covalent bond, towards itself.

Effective nuclear charge is the the net positive charge experienced by an electron in a multi-electron atom.

Electronegativity value increases as the effective nuclear charge on the atomic nucleus increases.

Electronegativity $\alpha$ Effective nuclear charge ($Z_{eff}$)
