Question

What is the electronic configuration of Rubidium?

Answer 1

Electronic configuration: The arrangement of electrons into the orbitals of an atom using some fundamental principle is called its electronic configuration.

Electronic configuration of Rubidium:

• The atomic symbol of Rubidium is $\mathrm{Rb}$.
• The atomic number of Rubidium is $37$ and it is a part of the alkali metal family.
• As the atomic number is equal to the number of electrons present in a neutral element. So, the number of electrons are $37$.
• The electronic configuration of Rubidium is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^{10}4{\mathrm{p}}^{6}5{\mathrm{s}}^1$.
• The electronic configuration of Rubidium in noble gas notation is represented as $\left[\mathrm{Kr}\right]5{\mathrm{s}}^1$.
