The atomic radii of group 1 elemetns of the periodic table are as follows:
`Na (186 "pm"), Li (152 "pm"), R(244"pm"),Cs(262"pm")` and `K(231"pm")`.
(a) Arrange these element in the increasing order of their atomic radii in a vertical column (keeping the element with the smallest atomic radius at the top).
(b) Which elements have the smallest and largest atoms?
(c) From this data, infer how the size (or atomic radius) of elements vary as we go doen in the group

Arrange the given elements in increasing order of their atomic radii? Li, Be, F and N

Arrange the increasing order of atomic radii Li, Na, K.

Name the elements which have the smallest and the largest atoms.

Arrange the following elements in increasing order of their atomic radii. Li, Be, F, N

Arrange the following elements in increasing order of their atomic radii. Cl, At, Br I

The atomic radii of the elements of second period are given below: (a) Arrange these elements in the decreasing order of their atomic radii (Keeping the element with the largest atomic radius first). (b) Are the elements now arranged in the pattern of a period in the periodic table? (c) Which elements have the largest and the smallest atoms? (d) From this data, infer how the atomic size (or atomic radius) of the elements changes as you go from left to right in a period?

Arrange the above elements vertically downwards in an increasing order of atomic radii.
