Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two semi-valence electrons which can be loaned out.
There are different ideas of what an electron is. One idea syas that an electron is part of an atom. Depending on the kind of atom, an atom can have 1 to 103 electrons. Each electron is extremely tiny. The mass (weight) of an electron is approximately equal to 1/1836 that of a hydrogen atom, which has one electron and one proton, so an electron is 1/1836th the size of a proton. Electrons carry a small electronically negative charge. In this model, electrons are in constant motion around the center of the atom.
