What is the difference between potassium-39 and potassium 41?
Since K is atomic number 19, it has 19 protons. It would need 20 neutrons to get to K 39. So K 41 has 19 protons and 22 protons. The difference between each of those isotopes is 2 neutrons.
Why is potassium-39 the most abundant?
All potassium atoms have 19 protons in the nucleus. The most common isotope of potassium is potassium-39. This means it adds 20 neutrons to the 19…

Why is potassium-39 the most abundant in nature?
Why does potassium 40 have a different mass number for potassium-39?
This difference is enough to make potassium 40 unstable. The reason for this is that protons, like neutrons, like to exist in pairs in a nucleus. Potassium 40 contains odd numbers of both – 19 protons and 21 neutrons.
What is the difference between K 41 and K?
K-41 is one of the naturally occurring isotopes of potassium. Use the periodic table to explain how the structure of K-41 differs from the normal K atom. K-41 has a total of 24 neutrons and normal K atom has 22 neutrons. K-41 has a total of 22 neutrons and normal K atom has 20 neutrons.
