Here are the atomic radii (in pm) for the third row of the periodic table: Na Mg Al Si P S CI Ar 186 160 143 118 110 103 100 98 Another property of atoms is called the ionization energy. It is the energy required to remove an electron from an atom in the gas phase. Here is a table of the first ionization energies (energy required to remove the outermost electron) for the third row of the periodic table (in kJ/mol): Na Mg Al Si P S CI Ar 496 738 577 788 1060 1000 1258 1520
