How does potassium-19 differ from potassium-41?
The nomenclature "potassium-19" is not commonly used because it is redundant. The 19 in potassium-19 would indicate the number of protons in potassium. All isotopes of potassium have 19 protons. Therefore 19 is known as the atomic number of potassium. Potassium-41 is one of the three naturally occurring isotopes of potassium. It has 19 protons and 22 neutrons, giving it an atomic mass number of 41.
