Aluminum has 13 protons and approximately 14 neutrons.
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
there are 12 nuetrons in an atom of magnesium
im eleven and i know the answer the answer is 18 nuetrons
protons and nuetrons are equal to no. of electrons present in atom
26 nuetrons, 22 electrons, and 22 protons
