I'm assuming you are referring to Potassium (K)-40.
All Potassium has 19 protons, though there are many stable isotopes.
Potassium-40 has 21 neutrons.

How many neutrons does potassium have'?
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39. Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
