Question

What is the electron configuration of 59 Pr (Praseodymium)?

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 Praseodymium(Pr):

• The atomic number of $\mathrm{Pr}$ is $59$.
• The electronic configuration will be $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}4{\mathrm{s}}^{2}4{\mathrm{p}}^{6}4{\mathrm{d}}^{10}5{\mathrm{s}}^{2}5{\mathrm{p}}^{6}4{\mathrm{f}}^{3}6{\mathrm{s}}^2$.
• The electronic configuration can be written as: $\left[\mathrm{Xe}\right]4{\mathrm{f}}^{3}6{\mathrm{s}}^2$
