How many protons, neutrons, and electrons are in aluminum?
The number of protons is the same number as the atomic number of the element on the periodic tableThe number of electrons is the same as the number of protonsTo get the number of neutrons, you take the average atomic mass(also given with the element on the periodic table) and subtract from it the number of protons(the atomic number)That gives you the number of neutrons there areThis is because each unit of a proton or neutron weighs 1 amu(the mass of the electron is insignifigant because it is so extremely tiny)The atomic mass given on the table is in amu'stherefore, subtracting the protons from it gives you the neutronsbtw, there can be more or less neutrons than protons because they have a charge of 0, so they don't affect the atomthe protons have a charge of 1 and electrons are -1, so generally, they like to keep balancedi hope i've explained this well enough for you
