See explanation below.

Work Step by Step

The range in electronegativity across the first (3d) transition series is 1.3 to 1.9. The range across Period 4 of the main-group elements is 0.8 to 2.8. In transition elements, electrons occupy d-orbitals, which shield the nuclear charge and make electrons to share between transition metal and bonded atom,because of this, the range is smaller for transition elements
