Solution

Identify the chemical symbol of Potassium:

The chemical symbol of Potassium is K.

The atomic number of Potassium is 19.

Identify the number of electrons and protons:

Atomic number = number of electrons = number of protons

Thus,

Number of electrons = 19

Number of protons = 19

Write the electronic configuration for Potassium:

1. The number of electrons in Potassium is 19.

2. The first K shell occupies 2 electrons, 8 electrons in the L shell, 8 in the M shell, and 1 electron in the L shell.

3. Thus, the electronic configuration of Potassium is K=2, L=8, M=8, and L=1.
