protons: neutrons: electrons: what is the total charge? 0

Explanation:

Step1: Recall charge of particles

Protons have a charge of + 1, neutrons have a charge of 0, and electrons have a charge of - 1.

Step2: Count particles

There is 1 proton (+1 charge), 1 neutron (0 charge), and 0 electrons (0 charge).

Step3: Calculate total charge

Total charge = charge of protons+charge of neutrons + charge of electrons = 1+0 + 0=1.
