Hydrogen possesses fewer valence electrons than lithium.

False.

Explanation: H and Li are both in Group 1. They both have one valence electron.

The Lewis dot structure for aluminum includes the symbol "Al" and a total of three dots around the symbol.

True.

Explanation: The Lewis structure for Al is ·Al:

An atom's electron affinity value indicates how favorable it is for the atom to form a negatively charged ion.

True.

The electron affinity is the energy absorbed or released when a neutral atom gains an electron. The more energy that is released, the more stable the ion,

The name of the ion P³⁻ is phosphoride ion.

False

Explanation: The name of P³⁻ is phosphide. The stem name of phosphorus in binary ionic compounds is “phosph-.”
