    False, True

    Explanation:

    False

    The atomic number of H and Li are 1 and 3 respectively. Atomic number is equal to the number of protons which is eqaul to the number of electrons. The electron configuration of H and Li are as follows:

    H = 1s¹

    Li = 1s² 2s¹

    The valence electrons of both H and Li are 1.

    True

    Al has 3 valance electrons. Hence the Lewis dot structure for aluminum includes the symbol, "Al," and a total of three dots around the symbol.

    True

    Electron affinity is the amount of of energy released or absorbed when an electron is added to a neutral gaseous atom to form a negatively charged ion.

    False

    The name of the ion P³⁻ is phosphide ion.

    Hydrogen possesses fewer valence electrons than lithium.

    Answer: 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.

    Answer: 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.

    Answer: 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.

    Answer: False

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