# Question #057bc

2+

#### Explanation:

The charge of the ion here would be +2.

Ions are atoms which have either lost or gained electrons. This makes them become charged.

Each proton has a charge of +1 and each electron is -1

25 protons = +25
23 electrons = -23

Net charge = (+25) + (-23) = -2

You can identify an ion by the number of protons, this is called the atomic number.

Element 25 = Manganese

So the ion you are asking about is $M {n}^{2 +}$
