Answer:
The correct option is;
c. Bromine, zinc, calcium, radium
Explanation:
The atomic radii of the elements as arranged in the periodic table decreases across the period and increases down the groups
The location of each of the elements are;
Zinc: Period 4, Group 12
Calcium: Period 4, Group 2
Radium: Period 7, Group 2
Bromine: Period 4, Group 17
Therefore, the element with the largest atomic radius = Radium
The element with the smallest atomic radius = Bromine
Calcium comes before zinc on period 4, therefore, the atomic radius of calcium is larger than that of zinc
The rank of the elements from smallest to largest atomic radius is therefore;
Bromine, zinc, calcium, radium.
