Potassium is among the alkali metals. Every one of the alkali metals have a solitary valence electron in the outer electron shell, which is easily removed to produce an ion v a hopeful charge – a cation, which combines v anions to type salts. Naturally occurring potassium is written of 3 isotopes, of i m sorry 40K is radioactive. Traces that 40K are discovered in all potassium, and it is the most usual radioisotope in the person body.

Agricultural fertilizers consume 95% of global potassium chemical production, and about 90% the this potassium is gave as KCl. As result of its high level of reactivity, pure potassium is rarely offered in its element /metallic form.
Potassium compounds have the right to be extracted from the earth as it is found in numerous solids, soil and seawater.
Protons and Neutrons in Potassium
The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is provided the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the spirit number and the atomic number is recognized as the neutron excess: D = N – Z = A – 2Z.
For secure elements, there is normally a variety of secure isotopes. Isotopes room nuclides that have the very same atomic number and are therefore the exact same element, yet differ in the variety of neutrons. Mass numbers of common isotopes the Potassium are 39; 41.
Main isotope of Potassium
There room 25 known isotopes of potassium, 3 of which occur naturally: 39K (93.3%), 40K (0.0117%), and 41K (6.7%).
Potassium-39 is created of 19 protons, 20 neutrons, and 19 electrons.

Potassium-40 is created of 19 protons, 21 neutrons, and 19 electrons. Traces that K-40 are found in every potassium, and also it is the most typical radioisotope in the human body. K-40 is a radioactive isotope the potassium which has a really long half-life the 1.251×109 years and also undergoes both types of beta decay.
