From the metals copper, iron, magnesium, sodium and zinc, select from metal which can form `2^(+)` and `3^(+)` ions

Explanation

To solve the problem of selecting a metal from copper, iron, magnesium, sodium, and zinc that can form both \(2^{+}\) and \(3^{+}\) ions, we can follow these steps:

### Step 1: Identify the oxidation states of each metal
- **Copper (Cu)**: Can form \(Cu^{+}\) (1+) and \(Cu^{2+}\) (2+) ions.
- **Iron (Fe)**: Can form \(Fe^{2+}\) (2+) and \(Fe^{3+}\) (3+) ions.
- **Magnesium (Mg)**: Only forms \(Mg^{2+}\) (2+) ions.
- **Sodium (Na)**: Only forms \(Na^{+}\) (1+) ions.
- **Zinc (Zn)**: Only forms \(Zn^{2+}\) (2+) ions.
