36 electrons (white) occupy eight shells (rings) fill the outermost (fourth) electron shell in a very stable configuration. The stability of the outermost electrons (valence) of an element determines its chemical and physical properties. Krypton is a noble gas of group 18, period 4 and block of the periodic table.
Since crypto is on the far right of the periodic table, its outer shell is filled with eight electrons. It is one of the elements of happiness and has an electronic configuration of 28188. The other noble gases, including argon and xenon, also have outer shells with eight electrons.
Each shell can only hold a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10 . ), etc. As a general formula, the nth shell can in principle contain a maximum of 2 (n2) electrons.

It’s not just Superman’s home planet, Krypton, one of the rarest gases on earth, which by volume makes up only one part per million of the atmosphere. This noble gas is colorless and odorless. It has an outer shell complete with electrons, which makes it largely inert to reactions with other elements.
Krypton (from ancient Greek: κρυπτός, Romanized: Kryptos the hidden) is a chemical element with the symbol Kr and the atomic number 36. It is a colorless, odorless and tasteless noble gas found in trace amounts in the atmosphere and is common with other noble gases used in fluorescent lamps.
The chemical element krypton is classified as a noble gas and as a non-metal.
Krypton has atomic number 36 and electron configuration. The Krypton Pup shell is the fourth, which is why there are 8 electrons in this valence shell.
Krypton reacts with fluorine, F2, when cooled to 196 ° C (liquid nitrogen) and exploited with electric discharge or X-rays, forming krypton (II) fluoride, KrF2. This compound is decomposed by heating to room temperature. Other halogens do not react with krypton.
The number of electrons in a neutral atom equals the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the atomic number (M) and the atomic number (Z).
The mass number (symbol A, from the German word atomic weight [atomic weight]), also called atomic number or number of nucleons, is the total number of protons and neutrons (called nucleons together) in an atomic nucleus. The mass number is different for each isotope of a chemical element.
In fact, the number of protons and electrons in an atom is the same only if the atom is neutral. The three atomic particles in an atom are protons that carry a positive charge, electrons that carry a negative charge, and neutrons that have no charge.
Two chemists, William Ramsay and Morris William Travers, who work at University College London, discovered krypton on May 30, 1898. They probably separated another element and named it krypton. The name comes from the Greek word kryptos, which means hidden.
