Question

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

Short answer

The match of spheres with the atoms is $B$is $K$, $D$is $Ce$, $A$is$Ge$and$C$is$Kr$.

Step-by-step solution

Given Information 

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

Explanation 

Now, The order of size of the element is-

$K>Ca>Ge>Kr$As 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 $D$is of $Ca$, $A$is of $Ge$and $C$is of$Kr$.
