Does potassium have naturally occuring isotopes?
Yes, it has the following three: 39K (93.3%), 40K (0.0117%), and 41K (6.7%).
There are 2 naturally occuring isotopes of Rubidium 85 Rb Mass 84.91u Mass 85.47u 87 Rb Mass 86.82u What is the percent abundance of each of the isotope?
When the masses of all naturally occurring isotopes of a particular element are averaged the result is called an elements what?
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.
