Answer:
2-; anion
Explanation:
1. Charge
Charge = +8 - 10 = -2
However, when we talk about the charge on an ion, we put the number first, so we say charge is 2-.
2. Type of ion
The ion has a negative charge, so it is an anion.
The nucleus has eight protons (oxygen), so it is an oxyanion.
The symbol for an oxyanion with two negative charges is O²⁻, and its name is the oxide ion.
