Question

Arrange the following in the basis of increasing non metallic character
B,C,Si,N and F

Answer 1

Answer:

Si,B,C,N,F

Explanation:

As we go down the table non-metallic character decreases ,and as we go right to left the non-metallic character increases.Notify me if I am wrong...☺️

Answer 2

Answer:

On moving from right to left in a period, the non-metallic character decreases (metallic character increases), as the atomic size increases and the force of attraction between the nucleus and the outermost electron decreases.

On moving from right to left in a period, the non-metallic character decreases (metallic character increases), as the atomic size increases and the force of attraction between the nucleus and the outermost electron decreases.Therefore, on moving from right to left in a period, the ability to gain electron (non-metallic character) decreases. Therefore, the order is Li<Be<C<O<F.
