A nuetral atom of potassium has an electron configuration of 2, 8, 8, 1. It is +ve 1 .

Looking at paotassium, atomic #= 19 , therefore there are 19 electrons. The electron configuration would be - 1s2 2s2 2p6 3s2 3p6 4s1. Then adding exponents- 2+2+6+2+6+1=19 which is the atomic number and therefore the number of electrons. This means that every atom of potassium has 19 protons in its nucleus.

Potassium (K) atom has 19 electrons. The full electron configuration of Potassium (K) is 1s22s22p63s23p64s1. The abbreviated form - [Ar]4s1 - means the electron configuration of Argon (Ar), plus one electron in the 4s orbital.

FAQ

Those who are looking for an answer to the question «What is the electron arrangement for potassium atomic number 19 )?» often ask the following questions:

### 😎 What is electron group arrangement?

• What is the electron group arrangement? Because the negative charges repel one another, the electron groups arrange themselves so they are as far apart as possible. This is the “Valence Shell Electron Pair Repulsion” (VSEPR) Theory. A “group” of electrons can be a single bond, double bond, triple bond, or a lone pair of electrons.
