Chapter 4: Q. 2.87 (page 131)

Match the spheres A through D with atoms of LI, Na, K, and Rb. 4.7

Short Answer

Expert verified

The match of spheres with the atoms is Bis Rb, Cis K,AisNaandDisLi.

Step by step solution

01

Given Information

We need to find the match the spheres A through D with atoms of LI, Na, K, and Rb.

02

Explanation

Li, Na, K, and Rb all the elements are in a group 1Aand different periods. In the periodic table size of elements increases when we go down the group. So the order of size is - Li<Na<K<Rb. And we can see by observing the image, the sequence of spheres is D<A<C<B.

So, from the sequence the largest sphere is B, so this is of Rb. And following the sequence sphere Cis of K, sphere Ais of Naand sphere Dis of Li.
