Atomic adius (pm)231 186. 244 264 152 Find out the groups to which above the elements belong, 2) Arrange the about elements vertically downwards in an increasing order tomic radii. Does this arrangement match with the pattern of the group 1 of the modern periodic table? Which of the above elements have the biggest and the smallest atom 51 What the periodic trend observed in variation of atomic radii downoup oup?​

Answer 1

Answer: Order of arrangement in the increasing order of their atomic radii

Cs , Na , K , Rb.

All these are group 1 elements
