Question

Arrange the following elements in decreasing order of atomic radius.

$O,N,F,C,B$

• A. $O<N<F<B<C$
• B. $B<C<N<O<F$
• C. $F<O<N<C<B$
• D. $N<O<F<B<C$

Answer 1

The correct option is C $F<O<N<C<B$

We know that, Atomic radii increases down the group and decreases along a period. Hence, the correct order of atomic radii of the given atoms is:

F < O < N < C < B. Hence, option C is correct.
