How to make an aluminum atom model?

First find out how many protons and neutrons it has. The number of protons and protons are equal to its atomic number on the periodic table. Its atomic weight (usually shown on the periodic table in smaller print), is roughly equal to the protons plus the neutrons. So if you subtract the protons from the atomic weight you should see about how many neutrons there are. The protons and neutrons are together in the nucleus. IIRC the protons shouldn’t be touching eachother. Finally, each row on the periodic table represents a separate electron orbit. So there are two electrons sharing the orbit closest to the nucleus, kinda like having two planet mercuries next to the sun. That’s because there are only two atoms on the first row of the periodic table, hydrogen and helium. Continue adding electrons to the appropriate orbits until you reach aluminum on the periodic table.

First, find out how many protons, neutrons and electrons are there in an aluminium atom. The atomic mass of an aluminium atom is 13 which means there are 13 protons. Since the number of protons equals to the number of electrons, there are also 13 electrons. The nucleon number is 27 thus the number of neutrons is derived by subtracting the atomic mass number from the nucleon number (27-13=14).

Then, paint 13 half-inch styrofoam balls green which represents protons, paint

Then, paint 13 half-inch styrofoam balls green which represents protons, paint 14 half-inch styrofoam balls yellow to represent neutrons. Also, paint 13 quarter-inch styrofoam balls black to represent electrons. Create the nucleus by gluing the green and yellow balls together into a large group.

The electronic configuration of an aluminium atom is 2.8.1. Thread two black Styrofoam balls onto a wire. Thread eight black Styrofoam balls onto a second wire. Thread the three black Styrofoam balls onto a third wire. Then, tie the black styrofoam balls together with the nucleus to form an aluminium atom.
