# What is more abundant 41K or 39K?

## What is more abundant 41K or 39K?

Potassium is known to have three naturally occurring isotopes (39K, 40K and 41K) with 40K having a low natural abundance. The atomic mass of potassium is 39.1 amu. 39K must be more abundant that 41K.

## How many protons does k 41?

19
Properties of Potassium-41 Isotope:

Properties of Potassium-41 Isotope: POTASSIUM-41
Atomic Number (Z) 19
Mass Number (A) 41
Nucleon Number (A) 41
Proton Number (Z) 19

How many protons neutrons and electrons does 41K have?

Potassium-41 is composed of 19 protons, 22 neutrons, and 19 electrons.

How many protons are there in potassium-41 isotope?

19 protons
Hence, number of neutrons is 40 – 19 which is 21. Potassium-41 – It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 – 19 which is 22.

### Which isotope is more abundant potassium?

potassium-39
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 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.

How many neutrons does 39k have?

20 neutrons
Hence, we can say that there are 19 protons, 20 neutrons and 18 electrons are present in \$^{39}{{K}_{19}}^{+}\$.

How many neutrons are in 41K?

22
Properties of 41K Isotope:

Properties of 41K Isotope: 41K
Neutron Number (N) 22
Atomic Number (Z) 19
Mass Number (A) 41
Nucleon Number (A) 41

#### How are potassium potassium 40 and potassium 41 different from each other?

They are different in their masses or mass number. Potassium- 39 has an atomic mass of 39 amu or mass number is 39, Potassium- 40 has an atomic mass of 40 amuor mass number is 40, and Potassium- 41 has an atomic mass of 41 amuor mass number is 41. The three isotopes have different numbers of neutrons.
