Question
A simple ion with a $3+$ charge (for example, $\mathrm{Al}^{3+} )$ results when an atom (gains/loses)_________ electrons.
Step 1
An atom consists of protons, neutrons, and electrons. Protons carry a positive charge, electrons carry a negative charge, and neutrons are neutral. In a neutral atom, the number of protons equals the number of electrons, so the positive and negative charges Show more…
