Chapter 4: Q. 4.88 (page 131)

Match the spheres A through D with atoms of K, Ge ,Ca, and Kr: (4.7)

Short Answer

Expert verified

The match of spheres with the atoms is Bis K, Dis Ce, AisGeandCisKr.

Step by step solution

01

Given Information 

We need to find the match the spheres A through D with atoms of K, Ge , Ca, and Kr.

02

Explanation 

Now, The order of size of the element is-

K>Ca>Ge>KrAs we can see by observing the image, the sequence of spheres is

B>D>A>C.

Therefore from the sequence the largest sphere is B, so this is of K. And following the sequence sphere Dis of Ca, Ais of Geand Cis ofKr.
