(a) atomic radius increases down a group of the periodic table from top to bottom (b) atomic radius decreases across a period of the periodic table from left to right. GO: GO with the Game Plan (i) lead, tin and silicon below to the same group of the periodic table (group 14). Lead (atomic symbol: Pb, atomic number: 82) is a Block P, Group 14, Period 6 element with an atomic radius of 207.2. The number of electrons in each of Lead's shells is [2, 8, 18, 32, 18, 4] and its electron configuration is [Xe] 4f 14 5d 10 6s 2 6p 2 . Note: Learn more about the atomic radius here.
