Question

Write the electronic configuration of potassium.

Answer 1

Definition of electronic configuration.

• The arrangement of electrons in various energy levels of an element is called electronic configuration.
• The maximum number of electrons which can be accommodated in any shell of an atom is given by 2n^2.
• Atomic number of potassium = 19
• Electronic configuration = 2,8,8,1 (K- shell = 2 electrons, L-shell = 8 electrons, M - shell = 8 electron, N - shell = 1 electron).
