Solution Steps

Step 1: Identify the Element

The element with 30 protons is zinc (Zn), as the atomic number of zinc is 30.

Step 2: Determine the Charge of the Ion

Zinc typically has 30 protons and 30 electrons in its neutral state. Given that there are 28 electrons in this case, the ion has lost 2 electrons.

Step 3: Calculate the Ion's Charge

The charge of the ion is determined by the difference between the number of protons and electrons. Since there are 2 fewer electrons than protons: \[ \text{Charge} = 30 - 28 = +2 \]

Final Answer

\[ \boxed{\mathrm{Zn}^{2+}} \]
