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.
