There is 1 electron in the outer shell of a potassium atom. The electron configuration is [Ar] 4s1. The orbitals with quantum numbers 1, 2 and 3 are all full so they are considered core orbitals.

There is one electron remaining and it happens to be the only one on the outer orbit. So the answer is one. If you want to figure this out your self, look at the vertical rows, the first one is H,Li,Na,K,Rb,Cs,Fr. All of those have 1 electron on the outer orbit. The 2nd vertical row all have 2 on the outer orbit, the 3rd vertical row all have 3 electrons on the outer orbit and so on. Don't you love how a Periodic Table is set-up? The vertical rows correspond with the outer electrons.

Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
How many electrons are in potassium's innermost energy level?
there are 2 electrons in potassium's innermost energy level
How many outer electrons in krypton?
The outer electrons in krypton are eight electrons.

How many electrons does potassium have on its outer shell?
1
How many electrons are there in potassium's outer energy level after the bond has formed?
One electron.
How many electrons are in the outer ring of potassium?
1 in the 4s orbital, 19 electrons in all (K has an atomic number of 19)
How many electrons does potassium need to loss to get a full outer shell?
One, its only valence electron.
How many electrons to make potassium happy?
Potassium (K) typically has 1 valence electron. It readily loses the lone outer electron leaving a strong shell of 8.
A potassium atom has how many electrons?
The neutral atom of potassium has 19 electrons.
How many electrons are in the outer shell of sodium lithium and potassium?
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
How many electrons does a potassium ion have?
Potassium ion has 18 electrons.
How many outer electrons does argon have?
Argon has 8 valence electrons (electrons in the outer shell)
How many electrons nitrogen has in its outer energy level and how many does bromine have?
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
How many valence electrons an potassium?
the valency of potassium is 1
