Cm ( Z =96) have [ Rn ] 5 f 7 6 d 1 7 s 2 Lr( Z =103) have [ Rn ] 5 f 14 6 d 1 7 s 2 Np ( Z =93) have [ Rn ] 5 f 4 6 d 1 7 s 2

Q. The general electronic configuration of actinides is $(n - 2)$ $f^{1 - 14} (n - 1) d^{0 - 1} n s^{2} .$ Which one of the following actinides has one electron in $6 d$ -orbital?

Cm ( Z = 96)

Lr ( Z = 103)

Np (Z = 93)

All of these

$C m (Z = 96)$ have $[R n] 5 f^{7} 6 d^{1} 7 s^{2}$

$L r (Z = 103)$ have $[R n] 5 f^{14} 6 d^{1} 7 s^{2}$

$Np (Z = 93)$ have $[R n] 5 f^{4} 6 d^{1} 7 s^{2}$
