Question

What is the electronic configuration of Scandium?

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 Scandium:

• The atomic symbol of Scandium is $\mathrm{Sc}$.
• The atomic number of Scandium is $21$.
• The atomic number of an element is equal to the number of electrons present in a neutral atom.
• So, the number of electrons are $21$.
• The electronic configuration of Scandium should be $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^1$.
• It can be written as also: $\left[\mathrm{Ar}\right]4{\mathrm{s}}^{2}3{\mathrm{d}}^1$
