Question

Which from following statements regarding transition elements is NOT correct?

विकल्प

• Ionic radii of these elements are smaller than ionic radii of representative elements of same period.

• Transition elements are more electropositive than elements of group 1 and group 2.

• These elements form ionic compounds in lower oxidation state.

• The ionization enthalpies of elements of third transition series are higher than elements of first transition series.

Answer 1

Transition elements are more electropositive than elements of group 1 and group 2.

Explanation:

The ionisation enthalpies of transition elements are intermediate between those of s-block and p-block elements. This indicates that transition elements are less electropositive than elements of group 1 and group 2.
