# What is the valence electron configuration for potassium?

K = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1. This simplifies to a noble gas notation of:K = [Ar] 4s^1

Potassium (K) is an Alkali metal found in the first column (Group I) and in the fourth row (period 4) of . All alkali metals end in s^1 for their .

The total electron configuration for potassium is

K = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1

This simplifies to a noble gas notation of

K = [Ar] 4s^1

We use the symbol for argon (Ar) because it is the last noble gas in the period (row) above potassium on the periodic table.

The are the highest energy level s and p orbital electrons of the atom. This would mean potassium has a valence shell of 4s^1
