Element	K	N	Rb	Cs	Li
Atomic radius	231	186	244	262	152

Question
(i) By referring to the Modern Periodic table find out the group to which above elements belong?
(ii) Arrange the above elements vertically downwards in an increasing order of atomic radii.
(iii) Does this arrangement match with the pattern of the group 1 of the Modern Periodic table?
(iv) Which of the above elements have the biggest and the smallest atom?
(v) What is the periodic trend observed in the variation of atomic radii down a groups?

✓

Answer

(i) Above elements belong to group 1.
(ii)

Li	152
Na	186
K	231
Rb	244
Cs	262

(iii) Yes. As we go down a group number of shells increases, therefore the atomic radii also increases.
(iv) 'Cs' has the biggest atom and 'Li' has the smallest atom.
(v) Atomic radii increases down a group, as number of shells are adding one at a time.
