MCQ
Which element has smallest atomic size?
- ✓Fluorine
- BChlorine
- CBromine
- DLodine
✓
Answer
Correct option: A.
Fluorine
The atomic size increases down the group because new shells are added when we move along the group.
This increases the distance between the outermost electrons and the nucleus, so the atomic size increases inspite of the increase in nuclear charge.
Therefore, fluorine has the smallest atomic size in the group.
