WebThe covalent size of the Zn is greater than the Cu because Zn has 3 d 1 0 configuration, while Cu has 3 d 9 configuration. Hence, more the d electrons, more will be screening effect leading to lesser nuclear attraction for the outer 4 s orbital electrons, hence the size is lesser contracted. So, the effective nuclear charge of Cu will be more, due to lesser d electrons.
