Arrange the following elements in the order of their increasing non-metallic character Li, O, C, Be, F

A

F `lt` O `lt` C `lt` Be `lt` Li

B

Li `lt` Be `lt` C `lt` O `lt` F

C

F `lt` O `lt` C `lt` Be `lt` Li

D

F `lt` O `lt` Be `lt` C `lt` Li

Text Solution

Verified by Experts

The correct Answer is:
B
Li, O, C, Be, F belong to same period i.e, `2^("nd")` period. In a period on moving from left to right, non-metallic character increases. Thus, the order of increasing non-metallic character is Li `lt` Be `lt` C `lt` O `lt` F.
