In the periodic table, you will also see that the most stable isotope has an atomic mass around 39, so the most stable isotope is 39. So for potassium, 19 taken away from 39 leaves 20 neutrons. People rarely look at the world around them in atomic terms, unless perhaps they are scientists.

Neutrons from Muon-Catalyzed Fusion and Muon- Capture Processes in an 39th EPS Conference & 16th Int. Congress on Plasma Physics - 2012-01-01 K37, K61 and K91 give trends in K–K bond distances relative to electron orbit matter with a fast propagating shock wave, releasing protons with keV kinetic.

However, it is possible to remove electrons and not change the identity of an element. These are called ions. The charge on the ion tells you the number of electrons. For an atom or ion: Number of Protons = Atomic Number Number of Neutrons = Mass Number – Number of Protons In an Atom: Number of Electrons = Number of Protons In an Anion: Number of Electrons = Number of Protons added to absolute value of charge In a Cation: Number of Electrons = Number of Protons minus the charge Families: Alkali Metals (Li, Na, K, Rb, Cs, and Fr): All have one valence So for your question, the Periodic Table tells us that potassium has an Atomic Number of 19, so there are 19 protons and 19 electrons. The Periodic Table tells us that potassium has an Atomic Mass of ≈39. So there are 39 - 19 = 20 neutrons.
