What is the isotope of 40K?

Potassium-40
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%.

How many electrons does K-40 have?

Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons. Traces of K-40 are found in all potassium, and it is the most common radioisotope in the human body.

What is the atomic number of potassium 39?

19
Potassium-39 atom is the stable isotope of potassium with relative atomic mass 38.963707, 93.3 atom percent natural abundance and nuclear spin 3/2….4.3Related Element.

How many electrons does K 42 have?

Sources! An isotope if an atomic element with the same number of protons; however, the atomic mass and number of neutrons differs. Potassium is an element in the periodic table with the atomic number of 19 and the atomic mass of 39. This means that potassium alone contains 19 protons and electrons and 20 neutrons.

Why is 40k not an isotope?

Potassium-40 is a rare example of an isotope that undergoes both types of beta decay. In about 10.72% of events, it decays to argon-40 (40Ar) by electron capture (EC), with the emission of a neutrino and then a 1.460 MeV gamma ray.

How many protons neutrons and electrons are in 40k+?

19 protons, 20 neutrons and 18 electrons.
