Determine the number of protons, electrons, and neutrons present in an atom of sodium (na). explain how you determined your answer using complete sentences. (6 points)

11 protons
11 electrons
12 neutrons
The atomic number is 11. So that means that there are 11 protons. How ever many protons there are there will be the same amount of electrons. The mass is 22.9. Round the number to 23 and then subtract the amount of protons from 23 and then you have the amount of neutrons.
