Question:
Which one of the following atoms is smaller in size?
Which one of the following atoms is smaller in size?
Show Hint
In a period, atomic size decreases as we move from left to right.
Updated On: Apr 17, 2025
- F
- O
- N
- C
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Fluorine (F) has the smallest size among the given elements because as we move across a period from left to right, the atomic size decreases due to an increase in effective nuclear charge. Thus, fluorine, being the rightmost in the period, has the smallest atomic size.
