Question

which periodic trend is a measure of the tendency of an atom to attract a bonding pair of electrons?
o electronegativity
o shielding
o ionization energy
o ionic radii

Explanation:

Electronegativity measures an atom's ability to attract bonding - pair electrons. Shielding is about inner - electrons reducing nuclear attraction on outer electrons. Ionization energy is the energy to remove an electron. Ionic radii refer to the size of ions.

Answer:

A. electronegativity
