The atomic number of an element determines the number of protons in its nucleus. An atom of an element becomes a monoatomic ion when it loses or gains electrons, altering its net charge.

1. The atomic number of 13 corresponds to the element Aluminum (Al). In its neutral state, Aluminum has 13 electrons, equal to its number of protons.

2. If an Aluminum atom loses 3 electrons, it will have 10 electrons left. Losing electrons gives the atom a positive charge, so it becomes a cation.

3. Therefore, the monoatomic ion with an atomic number of 13 and 10 electrons is Al3+.
