Consider atomic number
Consider the atom's atomic number. This is the number of protons in the atom's nucleus.
Consider atomic mass number
Consider the atom's atomic mass number. This is the number of protons and neutrons in the nucleus.
Consider electronic configuration
Consider the atom's electronic configuration. The electrons in an atom have fixed orbits with discrete energy levels. Atoms whose outer energy levels are full are less reactive than those with unfilled energy levels.
