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?

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?

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?

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.

Is potassium 40 radioactive?

Potassium-40 (40K) is a naturally occurring radioactive isotope of the common element potassium (potassium represents about 2.4% by weight of the earth’s crust). The half-life of 40K is 1.248 x 109 years [1]  its origins are primordial. 40K has an atomic percent abundance of 0.0117%.

What are two likely isotopes for potassium?

Although Potassium only has two stable isotopes (K-39 and K-41), the long-lived radioisotope K-40 is often also regarded as a stable isotope. Potassium Isotopes, mainly K-40 and K-41, are used to study the impact of potassium on the growth of plants and of the human cardiovascular system.
