As you go down a column, atomic radius increases. Carbon is in the highest row, meaning that it has the smallest atomic radius. Silicon and sodium are in the same row, but because of the fact that atomic radius decreases as you go across a row, silicon has a larger radius than sodium. 5. In order of decreasing ionization energy: fluorine, nitrogen, phosphorous. As you go across a row, ionization energy increases. Fluorine is in the rightmost column, meaning that it has the greatest ionization energy. Since ionization energy decreases as you go down a column, nitrogen needs more
