Answer

Explanation:

Step1: Identify gallium's position

Gallium (Ga) is in group 13 of the periodic table. Elements in group 13 have 3 valence - electrons.

Step2: Recall periodic - table group property

Elements in the same group of the periodic table have the same number of valence electrons. As we move from top to bottom in a group, the number of electron shells increases, but the number of valence electrons remains the same.

Answer:

  1. B. 3
  2. B. It stays the same
