We’re being asked to determine total number of electrons in a 31Ga3+ ion

Before we can do that, let’s first determine the total number of electrons in a neutral gallium atom by writing its electron configuration.

You can determine the ground-state electron configuration of Gallium (Ga) by locating the position Ga in the periodic table.

Ground-state means that the element is in its lowest energy form (not in excited state). Neutral neon means it has no charge, meaning no electrons are removed or added in the atom.

You can see in the above illustration of the periodic table that Ne is in Period 4, Group 3A, and p-block.
