               Answer:                  

Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell.

            Explanation:              

Atomic number of Potassium is 19

So it's configuration will be (2,8,8,1)

Valency is the combining capacity of an element as well as number of electrons in its valence shell.

i.e., the number of valence electrons in valence shell is 1

Thus it's valency is 1..
