• C. +1
• D. -2

Answer: (B)

Verified step by step guidance

1. Identify the number of protons and electrons in the ion. Here, the ion has 12 protons and 10 electrons.
2. Recall that protons carry a positive charge of +1 each, and electrons carry a negative charge of -1 each.
3. Calculate the total positive charge from protons: \$12 \times (+1) = +12$.
4. Calculate the total negative charge from electrons: \$10 \times (-1) = -10$.
5. Find the net charge of the ion by adding the total positive and negative charges: \(+12 + (-10) = +2\). This means the ion has a charge of +2.
