Solution: Which of the following correctly lists the five atoms in order of increasing size (smallest to largest)?A) F < K < Ge < Br < RbB) F < Ge < Br < K < RbC) F < K < Br < Ge < RbD) F < Br < Ge < K < RbE) F < Br < Ge < Rb < K 

Problem

Which of the following correctly lists the five atoms in order of increasing size (smallest to largest)?

A) F < K < Ge < Br < Rb

B) F < Ge < Br < K < Rb

C) F < K < Br < Ge < Rb

D) F < Br < Ge < K < Rb

E) F < Br < Ge < Rb < K 

Solution

We’re being asked to rank the elements in increasing atomic radius .


Atomic radius represents the distance from the nucleus to the outer shell of an element. 

The trend of the atomic radius in the periodic table:

decreases going from left to right of a period

increases going down a group
