as far as i know aluminum is a molecule not an atom.
The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.

Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus in energy levels.
Aluminium is an element and contains no particles of any 'other' matter. Like all elements, it's atoms contain protons, neutrons and electrons.
Aluminium has 13 electrons and protons; the number of neutrons is specific for each isotope.
Number of neutrons in an aluminium isotope = Mass number - 13
Two subatomic particles in the nucleus of any atom are protons and neutrons, except hydrogen atom with only 1 proton (no neutron).
Subatomic particles such as electrons, protons, and neutrons are smaller than an atom. Additionally, quarks and leptons are fundamental particles that make up subatomic particles.
Proton and neutron.
Neutrons are subatomic particles with no charge. They are found in the nucleus of an atom along with protons and contribute to the atomic mass of an element without affecting its charge.
Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.
Atoms are composed of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, with protons carrying a positive charge and neutrons having no charge. Electrons orbit around the nucleus and carry a negative charge.
