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

  • A
    electronegativity
  • Correct answer
    B
    atomic radius
  • C
    ionisation energy
  • D
    electron 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'.
