• C. +3
• D. -3

Answer: (C)

Verified step by step guidance

1. Identify the number of protons and electrons in the ion. Here, the ion has 13 protons and 10 electrons.
2. Recall that the charge of an ion is determined by the difference between the number of protons (positive charges) and electrons (negative charges).
3. Use the formula for ionic charge: \(\text{Charge} = \text{Number of protons} - \text{Number of electrons}\).
4. Substitute the given values into the formula: \(\text{Charge} = 13 - 10\).
5. Calculate the difference to find the ionic charge, which will be positive if there are more protons than electrons, indicating a cation.
