The electronegativity of the following elements increases in the order

A

`P, Si, N, C`

B

`Si, P, C, N`

C

`C, N, Si, P`

D

`N, Si, C, P`

Text Solution

Verified by Experts

The correct Answer is:
B
In general, electronegativity increases across the period on account of increase of `Z_(eff)` while it decreases on moving down the group due to increase of atomic size:

Thus, the correct order is
`Si (1.8) gt P (2.1) gt C (2.5) gt N(3.0)`

The electronegativity of the element C , N , Si and P increase in the order ………..

Atoms of metals have only a few electrons in their valence shells while atoms of non-metals generally have more electrons in their valence shells. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from left to right in a period. Metallic character is inversely related to electronegativity. The electronegativities of the following elements increase in the order
