Solution Steps

Step 1: Identify the neutral atom with 10 electrons

A neutral atom with 10 electrons is neon (Ne), which has an atomic number of 10.

Step 2: Identify cations with 10 electrons

To find cations with 10 electrons, we need to consider atoms that lose electrons to achieve 10 electrons.

  1. Sodium (Na) has an atomic number of 11. When it loses one electron, it becomes \( \text{Na}^+ \) with 10 electrons.
  2. Magnesium (Mg) has an atomic number of 12. When it loses two electrons, it becomes \( \text{Mg}^{2+} \) with 10 electrons.

Final Answer

\[ \boxed{\text{Ne}, \ \text{Na}^+, \ \text{Mg}^{2+}} \]
