Q82 / 160 · JIPMER 2010 · Chemistry
Which of the following is a wrong statement? In a given period of the Periodic Table, the $s$-block element has, in general, a higher value of
- Aelectronegativity
- Correct answerBatomic radius
- Cionisation energy
- Delectron affinity
Solution
Electronegativity, ionisation energy and electron affinity of $s$-block elements in their respective period is low but the atomic radius of the $s$-block elements is larger in their respective period due to less effective nuclear charge.
Hence, the correct answer is option: 'B'.
