• Atomic Radius

• The likelihood that that an atom will participate in a chemical reaction

• Electronegativity

• The energy required to remove an electron from an atom.

• Reactivity

• The distance from the center of an atom and the furthest electron. This is a measure of an atom's size.

• Ionization Energy

• The strength of attraction between an atom's nucleus and the electrons in that atom.
