A nucleus of strong positive charge pulls its electron cloud towards itself tightly such that the latter would have a small radius. The periodic table is arranged in the order of increasing proton number. WebIonic radii are difficult to measure with any degree of certainty, and vary according to the environment of the ion. For example, it matters what the co-ordination of the ion is (how many oppositely charged ions are touching it), and what those ions are. bishop mcdevitt high school pennsylvania
