The electro-negativity of the following elements increases in the order

C, N, Si, P

N, Si, C, P

Si, P, C, N

P, Si, N, C​

Answer 1

Answer:

Si, P, C, N

Explanation:

Electro negativity decreases down a group and increases across a period. Therefore N will have the highest electronegativity and C will have less than N. Si and P will have less than both will E.N of P more than that of Si.

Answer 2

Answer:

Si<P<C<N

Explanation:

In a period, electronegativity increases from left to right.

In a group, the electronegativity decreases down the group.
