Last week we introduced our Far Too Simple Model Of An Atom© so we could talk about protons.
A more complete view of the atom includes two other particles:

- electrons, which are smaller, have a - on them, and are in motion in the orbitals, rather than the nucleus
PS You know which element this atom is. (answer)
