You also have potassium-- and once again writing the K and the 19 are a little bit redundant-- you also have potassium-41. So this would have 22 neutrons. 22 plus 19 is 41. This accounts for about 6.7% of the potassium on the planet. And then you have a very scarce isotope of potassium called potassium-40. Potassium-40 clearly has 21 neutrons.
