Draw the electronic configuration for a neutral atom of scandium

Answer 1

Scandium (Sc) has an atomic number of 21, meaning it has 21 electrons. The electronic configuration for a neutral atom of scandium can be written as:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹

This configuration shows the distribution of electrons in the different energy levels and subshells of an atom.
