Potassium is among the alkali metals. All of the alkali metals have a solitary valence electron in the outer electron shell, i m sorry is easily removed to produce an ion with a positive charge – a cation, i beg your pardon combines through anions to kind salts. Naturally emerging potassium is created of three isotopes, of i beg your pardon 40K is radioactive. Traces that 40K are uncovered in every potassium, and it is the most typical radioisotope in the human body.

Agricultural fertilizer consume 95% of an international potassium chemistry production, and around 90% of this potassium is gave as KCl. Due to its high degree of reactivity, pure potassium is rarely supplied in its element /metallic form.
Potassium compounds can be extract from the planet as the is found in numerous solids, soil and also seawater.
Protons and also Neutrons in Potassium
The full number of neutrons in the cell nucleus of an atom is called the neutron number of the atom and also is given the symbol N. Neutron number plus atomic number equals atom mass number: N+Z=A. The difference between the neutron number and the atom number is recognized as the neutron excess: D = N – Z = A – 2Z.
For stable elements, there is generally a selection of stable isotopes. Isotopes space nuclides that have the very same atomic number and also are therefore the very same element, but differ in the number of neutrons. Mass number of common isotopes the Potassium are 39; 41.
Main isotopes of Potassium
There space 25 known isotopes the potassium, three of which take place 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 also 19 electrons. Traces of K-40 are found in every potassium, and also it is the most usual radioisotope in the human body. K-40 is a radiation isotope the potassium which has actually a really long half-life that 1.251×109 years and undergoes both varieties of beta decay.
