Answer: 20 electrons

Explanation: Assuming that the atom is a neutral atom, it would have 20 protons in its nucleus. The atomic number is the number of protons in the nucleus of a certain kind of atom. In addition, it tells you the number of electrons if that atom is neutral so it would have 20 electrons.
