Question

Which one of the following is a $' d - block$ element '

Moderate

A

$Gd$
B

$Hs$
C

$Es$
D

$Cs$

Solution

$d - block$ elements have incompletely filled $d - orbitals$ in their ground state or in any of their oxidation states.
The general electronic configuration of $d - block$ elements is $(n - 1) d^{1 - 10} {ns}^{1 - 2}$ Depending on ( $n - 1$ ) values,
there are $3 d, 4 d, 5 d$ and $6 d$ series of transition elements.
$Hs$ ( $Z = 108$ ) [Hassium] belongs to 6d series with electronic configuration - $[Rn] 5 f^{14} 6 d^{6} 7 s^{2}$ .
