The charge of 3 protons and 2 electrons can be calculated as follows:

Protons have a positive charge of +1, while electrons have a negative charge of -1.

Charge of 3 protons = 3 x (+1) = +3

Charge of 2 electrons = 2 x (-1) = -2

Overall charge = Charge of protons + Charge of electrons

= +3 + (-2)

= +1

Therefore, the net charge of 3 protons and 2 electrons is +1.
