Noble gases have a full outer shell of electrons, which makes them stable and unreactive. For noble gases, the outer shell typically contains eight electrons, following the octet rule. This applies to all noble gases with atomic masses greater than three, such as neon, argon, krypton, xenon, and radon. Therefore, a noble gas with an Atomic Mass greater than three has eight electrons in its outer shell.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
Helium differs from other noble gases in its smaller atomic size and lower atomic mass. It is also the only noble gas that does not have a full shell of electrons, containing just 2 electrons in its outer shell. Additionally, helium is the least reactive of the noble gases due to its stable electron configuration.
Atomic mass does not directly indicate an element's reactivity. Reactivity is primarily determined by the number of electrons in the outer shell of an element (valence electrons). Elements with a full or nearly full outer shell (noble gases) are generally unreactive, while elements with few electrons in the outer shell (alkali metals) are highly reactive.
noble gasses have a full outer shell of 8 electrons which makes them fairly stable as they have no more room in that shell for another electron nor do they have the need to share there electrons with another element to gain a full outer shell
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
Arsenic, with an atomic number of 33, will gain 3 electrons to have a filled outer shell, achieving stability with 8 electrons in its outer shell like a noble gas.
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.

A metal typically has a greater atomic radius than its ionic radius. When a metal loses electrons to become a cation, the outer electrons are removed, leading to a decrease in the ionic radius compared to the neutral atom's atomic radius.

There are four electrons found on the outer shell of a atomic structure of tin. They are in a group of four.
