Smallest Atomic Radius
A group's atomic radius grows from top to bottom, while a period's atomic radius shrinks from left to right. Francium is, therefore the largest element, and helium is the smallest. The symbol for chlorine, which is the second-lightest halogen, is Cl. This chemical element has an atomic number of 17.
Uses of Chlorine (Cl)
- It is applied to eliminate the putrid odour.
- It serves as an antiseptic.
- To kill bacteria, chlorine is used to purify drinking water.
- Swimming pools are cleaned with it.
- It is employed in the manufacture of paper and paper goods.
- It functions as an antibiotic.
Hence, francium is the largest, and helium is the smallest element.
Which of the following elements has the smallest atomic radius? (A) Bromine (B) Chlorine (C) Sodium (D) Calcium
Chlorine's atomic radius is the shortest of those of bromine, chloride, sodium, and calcium. As a result, francium is the largest element while. It is utilized to make medications. It is employed in the production of polymers and dyes.
