Along the period, atomic/ionic radius and metallic character generally decreases, while IE, EN and nonmetallic character and oxidizing power increases.
  If the ionic radius of `M^(+)` and `X^(-)` are about 135 and 209 pm respectively, then the expected values of atomic radius of M and X may be respectively in pm)
(M and X are metal and non-metal, respectively of same period.)
