Periodic Classification and Periodic Properties - Result Question 23
####20. The electronegativity of the following elements increases in the order
(1987, 1M)
(a) $C, N, Si, P$
(b) $N, Si, C, P$
(c) $Si, P, C, N$
(d) P, Si, N, C
Show Answer
Answer:
Correct Answer: 20. (a)
Solution:
- Electronegativity increases from left to right in a period and decreases from top to bottom in a group. Variation is more rapid in group than in a period, hence the desired order is Electronegativity : $Si<P<C<N$
