If an atom has 14 protons, 12 neutrons, and 18 electrons, what is the atom's electrical charge?

a. - 4

b. 4

c. 6

d. - 6

14 - 18 = - 4

protons have a positive charge and electrons have a negative charge

there are more electrons so the charge will be negative

the neutrons can be ignored for this problem since they have no charge
