Question

What is the electron configuration of $C{u^ + }$ ?

Answer 1

Electronic configuration refers to a way in order to express how electrons get arranged in an atom. Plus, it helps to understand how covalent or ionic bonds are created.

Complete answer:
Electrical configuration of $Cu{2^ + }$ ion is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^9}.\;$ To obtain this configuration two electrons are removed from the shells of $Cu$ion. One is removed from $4{s^1}$ while other from $3{d^{10}}$.

The electrical configuration of Cu is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^{10}}4{s^1}$. When two electrons get removed from it we get the electrical configuration of $Cu{2^ + }$ ion.

Note:
Copper is an element that has an atomic number of thirty nine over the periodic table.
It refers to a soft as well as a ductile metal which can be drawn in the form of sheets and also, wires. It is said to be a good conductor of electricity as well as quite cheap as compared to silver that in turn also makes it feasible for utilization in electrical circuits.
