An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom. Then, explain how you determined the number of each type of particle. Use the periodic table to help you.
It contains 11 protons in the nucleus. It contains 12 neutrons in the nucleus. It contains 10 electrons surrounding the nucleus. The number of electrons are calculated from net charge and charge of proton (+1) and electron (–1). 12 neutrons are calculated from atomic number: 11 and mass number: 23.
