Considering the element B, C, N, F and Si, the correct order of their non-metallic character to

Options

A. `B gt C gt Si gt N gt F`
B. `Si gt C gt B gt N gt F`
C. `F gt N gt C gt B gt Si`
D. `F gt N gt C gt Si gt B`

Answer

C

Explanation

On moving across a period from left to right, the non-metallic character of the elements increases. Thus, order of non-metallic character of the given elements is `F gt N gt C gt B`. However, on moving down a group, the non-metallic character of elements decreases. thus, Si is more non-metallic than C. thus, non-metallic character of the elements follows the sequence `F gt N gt C gt B gt Si`.
