Valence Electron Configuration for Potassium?

Question

What is the Valence Electron Configuration for Potassium?

Answer 1

Elecectron Configuration = 1 s2 2 s2 2 p6 3 s2 3 p6 4 s1

Valence Shel 4 s1

Hope that helps.

Answer 2

This element would have 6 valence electrons because there are 2 electrons on the s orbital and 4 electrons on the p orbital. The element is a member of group 6A. The elements having this valence shell configuration are O, S, Se, Te and Po. The formula of the element when combined with K is K2N (let N be the symbol of the element having the above valence shell configuration) The element would have a smaller radius than Ba. The element would have a smaller ionization energy than F. :)

Answer 3

It is [Ar],4S1. The expanded EC is 1S2,2S2,2P6,3S2,3P6,4S1.
