Considering the elements `B, C, N, F` and `Si`, the correct order of their non-metallic character is ?

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`

Explanation

The non-metallic character of elements increases from left to right across a period. Thus, the decreasing order of non-metallic character is `F gt N gt C gt B`.
Again, the non-metallic character of elements decreases down a group. Thus, the decreasing order of non-metallic characters of C and Si are `C gt Si`. However, Si is less non-metallic than B i.e., `B gt Si`.
Hence, the correct order of their non-metallic characters is `F gt N gt C gt B gt Si.`
