What is the atomic number and atomic mass number for aluminum?
The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the atomic mass number. One isotope is Al-27, in which there are 14 neutrons.
