Question

Which of the following has ns${}^2$ np${}^6$ nd${}^{10}$ (n+1)s${}^0$ configuration?

• A. $Pd$
• B. $A{g}^{+}$
• C. $C{d}^{+2}$
• D. All of the above

Answer 1

The correct option is D All of the above

$Pd$, $A{g}^{+}$ and $C{d}^{+2}$ are isoelectronic species as they all contain 46 electrons.
