What is the valence electron configuration for potassium?
This simplifies to a noble gas notation of:K =
The total electron configuration for potassium is
This simplifies to a noble gas notation of
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 valence electrons are the highest energy level s and p orbital electrons of the atom. This would mean potassium has a valence shell of
