Question

The atomic radius of zinc in first transition series increases instead of decreasing give reason.

Answer 1

As we are moving from sc to zc , initially one factor nuclear charge increases as the new electrons coming and entering into same orbital that to inner one , as the number of electrons are low in the inner shell and the shielding power of d orbial is low , inter electronic repulsions will be operating less than nuclear charge , which results in decrease in atomic radii....
