Co odd atomic number paramagnetic a. Ca < Sr < Rb Strontium has one more shell of electrons than calcium. It has one more electron and proton than rubidium, so it is smaller. Atomic radius increases from top to bottom in a group of elements and from right to left in a period of elements. b. C < Si < A1 Silicon has one more shell of electrons than carbon, so is larger. Silicon has one more electron and proton than aluminum, so is smaller. Atomic radius increases from top to bottom in a group of elements and from right to lefi in a period of elements. a. Ca is to the lefi of As so is larger in size and [Ca < 1A5. The hard choice is Ca and Na. The ionization energy increases to the right but decreases down. But the decrease down is less than the increase to the right, so Ica > INa. Na < Ca < As b. Sn is to the left and below As which is to the lefi and below S. Sn<As<S c.
