Question

What is the electron configuration of palladium?

Answer 1

Hint: Palladium belongs to group number $10$ and period number $5$ of the periodic number. It is represented by the symbol $Pd$ and its atomic number is $46$.It is one of the most expensive metals present in today’s date. It belongs to the platinum group.

Complete answer:
The electron configuration tells us about the distribution of electrons of any molecule in its molecular orbits.
The electron configuration of palladium is expressed as $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{0}4d^{10}$.
It can also be written as:$[Kr]4d^{10}$
Properties of palladium:
It is a silvery white coloured metal that can resist tarnishing.
It is considered as non toxic as it does not have any biological roles. Palladium is found in both combined state and detached state.
It is the most reactive among the platinum group elements. It is one of the transition metals that have a high tendency to bond with carbon.
Palladium compounds can easily be decomposed to liberate the metals. Most palladium compounds can exist in $+2$ and $0$ oxidation states.

Additional information:
Palladium is a Lindlar catalyst and at times is also referred to as Lindlar Palladium. It is used for making jewellery.As palladium is an absorbent of hydrogen , it is used for storage of the same. It serves as a metal catalyst in many chemical processes like hydrogenation and dehydrogenation.

Note:
When we are writing electron configurations, a standardized notation has to be followed in which the energy level and the type of orbital are written first, followed by the number of electrons present in the orbital written in superscript.
