I believe 24 isotopes have been identified with Atomic Mass ranging from 32 to 55. Only three occur naturally, K39 (93% of the total), K41 (7%) and the radioactive K40 (0.01%). The others have very short half-lives, as small as a few nano-seconds in some cases.
Potassium has multiple isotopes, such as potassium-39 and potassium-41, which have different numbers of neutrons in their nuclei. These isotopes do not affect the chemical properties of potassium, but they have different atomic masses due to the differing number of neutrons.
Atoms of the same element that differ in the number of neutrons they contain are know as isotopes. Isotopes are identified by their mass number. For example hydrogen with an extra neutron is called Deuterium.
Isotopes of potassium, like other isotopes of elements, have the same chemical properties because they have the same electron configuration. Consequently, their boiling and melting points are essentially identical. However, slight differences may arise due to variations in mass, but these differences are typically negligible and do not significantly affect the physical properties. Therefore, for practical purposes, potassium isotopes can be considered to have the same boiling and melting points.
K-37 and K-42 are isotopes of potassium because they have the same number of protons in their nuclei, which defines them as potassium. However, they have different numbers of neutrons, leading to variations in their atomic masses. Specifically, K-37 has 20 neutrons while K-42 has 25 neutrons. This difference in neutron count results in distinct isotopic forms of the element potassium.
Potassium has three naturally occurring isotopes: potassium-39, potassium-40, and potassium-41. The most common isotope is potassium-39, which makes up about 93% of naturally occurring potassium.

The numbers 39, 40, and 41 after the element name potassium refer to the mass number of the isotopes of potassium. Potassium has three isotopes: potassium-39, potassium-40, and potassium-41, which have 19, 20, and 21 neutrons respectively.
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
look at a periodic table :)
99.988% of potassium found in nature is not radioactive. 0.012% of natural potassium is 40K, which is radioactive and has a half life of about 1,248,000,000 years. Like all other elements, synthetic radioactive isotopes of potassium exist.
Potassium-39 and potassium-41 are isotopes of potassium, meaning they have the same number of protons but different numbers of neutrons. Potassium-39 has 20 neutrons, while potassium-41 has 22 neutrons. This difference in neutron number results in different atomic masses for the two isotopes.

Potassium occurs naturally on earth in three isotopes with mass numbers 39, 40, and 41. Of these, the isotope K-40 is known to be radioactive, but has a very long half life. There are many other radioactive isotopes of potassium.
The radioactive decay of potassium 40 produces in argon 40. The proportion of these two isotopes in rocks permit their age to be calculated.
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.
