Question

Considering the elements B, C, N, F, and Si, the correct order of their
non-metallic character is :
(a) B > C > Si > NF (b) Si > C >B>N>F
(c) F>N > C > B > Si (d) F >N> C > Si > B​

Answer 1

Answer:

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 > Si. However, Si is less non-metallic than B i.e., B > Si. Hence, the correct order of their non-metallic characters is F > N > C > B > Si.

Answer 2

Answer:

(c) F>N>C>B>Si is the answer
