Question

The atomic radii of group 1 elements of the periodic table are as follows : Na (186 pm), Li (152 pm), Rb (244 pm), Cs (262 pm) and K (231 pm). Which element has the largest atom ​

Answer 1

Answer:

The atomic radii of group 1 elemetns of the periodic table are as follows: <br> Na (186 "pm"), Li (152 "pm"), R(244"pm"),Cs(262"pm") and K(231"pm") . <br> (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). <br> (b) Which elements have the smallest and largest atoms? <br> (c) From this data, infer how the size (or atomic radius) of elements vary as we go doen in the group
