Question

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

Answer 1

11 protons, 12 neutrons, 10 electrons

Step-by-step explanation:

Sodium has an atomic number of 11, so it has 11 protons.

The atomic mass is 23, so there are 23 − 11 = 12 neutrons.

The charge is +1, so there is 1 more proton than electrons, so there are 10 electrons.
