Question:
Which one of the following indicates correct order of atomic size of the given elements?
Which one of the following indicates correct order of atomic size of the given elements?
Show Hint
Atomic size decreases across a period and increases down a group. This trend is key to determining the atomic size order.
Updated On: May 13, 2025
- Li $>$ B $>$ F $>$ N
- N $>$ F $>$ Li $>$ B
- F $>$ N $>$ B $>$ Li
- Li $>$ N $>$ B $>$ F
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The order of atomic size increases as you go down a group and decreases across a period in the periodic table. For the given elements, the atomic size decreases as we move from Li to F in the same period. Thus, the correct order is:
Li $>$ N $>$ B $>$ F.
