How many protons in al
Did you know?
WebAs an example, an aluminum atom has an atomic number of 13, reflecting the fact that it has 13 protons. Every proton has a positive charge, and since most atoms are neutral it follows that for every proton that there is an electron, for 13 electrons and 13 protons. This is true of all atoms of aluminum. Therefore, an aluminum atom has thirteen protons and thirteen electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. The difference between the mass number of the aluminum atom and the number of protons is fourteen.
