If an atom has 5 protons, 5 neutrons, and 3 electrons, the amom's charge is A. +2. charge=protons-electrons.

Let's see the charge of each particle first:

- proton: charge +1

- neutron: charge 0

- electron: charge -1


We have 5 protons, 5 neutrons and 3 electrons, so the total charge of the atom is:

[tex] Q=5 \cdot (+1) + 5 \cdot (0) + 3 \cdot (-1) =5+0-3=+2 [/tex]


So, the correct answer is

A. +2
