An atom with 7 protons, 8 neutrons, and 10 electrons has which of the following charges?

Question

Quizplus · Accepted Answer

The charge of an atom is determined by the difference between its number of protons and electrons. To calculate the charge of an atom, we subtract the number of electrons from the number of protons. The result is the net charge of the atom.
In this atom, there are 7 protons and 10 electrons.
7 - 10 = -3
Therefore, the atom's net charge is -3
Note whenever there are more electrons than protons, the atom has a negative charge.
