If an atom has 16 protons, 14 neutrons, and 19 electrons, what is the atom's electrical charge? A +2
B.-3
C.-2
D.-5

Thus, each atom or ion must contain 16 protons. We are told that the ion also has 14 neutrons, meaning the mass number of the ion is 16 + 14 = 30 Because the ion has 16 protons and 19 electrons, its net charge is -3.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
