In the d-block element only Cu +has no unpaired electron and it will have zero magnetic moment. Hence the element has atomic number z=29. and the element just below it has atomic number =29+18 =47

Q. A particular d-block element ' $A$ ' of $4^{th}$ period has zero magnetic moment when it is in $A^{+}$ state. Then find the atomic number of the element in the periodic table which is just below this element.

In the d-block element only $C u^{+}$ has no unpaired electron and it will have zero magnetic moment.
Hence the element has atomic number $z = 29$ .
and the element just below it has atomic number $= 29 + 18$
$= 47$
