an aluminum isotope consists of 13 protons, 13 electrons, and 14 neutronsits mass number is what?
27Mass number is protons plus nuetronsElectrons haven't got enough mass to be counted.
Aluminum has 13 protonsNo matter what the oxidation state is it will still have 13 protons in its nucleusThink: I the number of proton changes the atom will no longer be called Al because the atom is called Al because it has the atom 13 protons.
atomic number-13electronsprotons electronic configuration2,8,3 it donates the three electrons to complete the octet it is absolutely 13
Of course it is thirteenThe number of proton of an element is equal to the number of electron, provided that it is not an ion.
Looking at the periodic table, Aluminum's atomic number is 13Thus, Aluminum has 13 protons.
