Question

A lithium atom has three protons, three neutrons, and three electrons. What is the overall charge on this atom?
–3
0
+1
+3

Answer 1

The overall charge on an atom is determined by the difference between the number of protons (positive charge) and the number of electrons (negative charge). In this case, the lithium atom has 3 protons (positive charge) and 3 electrons (negative charge), so the overall charge of the atom is 0. Therefore, the answer is 0.
