Question

why atomic radius of Zn slightly increases ?​

Answer 1

Answer:

The atomic size from Cu to Zn slightly increases because shielding effect is more than the effective nuclear charge due to d10 structure of Cu and Zn. The atomic radii of the elements of 3d transition series are as under. ... This is due to the increase in number of shells with the increase in atomic number.
