Each atom of magnesium has a nucleus in the middle with twelve protons and twelve neutrons all packed together. Spinning around the nucleus are twelve electrons in three ’orbits.’ The first orbit (closest to the nucleus) has two electrons in it. The second one has eight, and the outside orbit has the last two.

This is a picture of magnesium from . The big problem with this picture is that it makes it look like the electrons are a lot bigger than the nucleus, when they’re actually a lot smaller:



You can also find some good pictures and a better explanation of how the atom works by looking at the answer to the question -Tamara
