Question

What is the condensed electron configuration of praseodymium?

Answer 1

Hint :In the given question firstly we have to define what exactly is the praseodymium and how can we determine it and give the proper definition and the characteristics of it. Like we can say that we can find the electron configuration of the praseodymium.

Complete Step By Step Answer:
The given question statement asks about the praseodymium and the main concepts of the molecular configuration of the praseodymium. Which should be determined in a step by step process.
The chemical of the praseodymium is a chemical element with the symbol Pr and the atomic number of the element would be 59. It is also the third member of the lanthanide series. It is also the one that is traditionally considered to be one of the rare-earth metals. It is also a soft and silvery, malleable and ductile metal which is highly valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air.
Now the electron configuration of the element depending on the characteristics of the element given in the explanation would be : \[[Xe]{\text{ }}4{f^3}\;6{s^2}\] .

Note :
Like most rare-earth elements, praseodymium most readily forms the +3 oxidation state, which is the only stable state in aqueous solution, although the +4 oxidation state is known in some solid compounds and, uniquely among the lanthanides, the +5 oxidation state is attainable in matrix-isolation conditions. Aqueous praseodymium ions are yellowish-green.
