This is the family of noble gases (group 18).
Group 18, the noble gases, contain a full octet of electrons. However, helium only has the s orbital which is full at 2 electrons.
They are the noble gases. They are group 8 elements
it is about 18th raw of periodic table. they have the full octet.

Group 18 (noble gases).
The noble gases.
The noble gases
it has a full octet
Krypton has 8 valence electrons that is 4s2 4p6.it is chemically inert since it attains an octet configuration.
The chemical elements tend to have 8 electrons in the valence shell.
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
These are the noble gases.
8 valence electrons
D. Noble Gases
Noble gasses have the complete octet of valence electrons. The are in the family 18 of the periodic table. They are unlikely to react with other elements.
An octet
it has a full octet
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
The octet rule.
Octet
the same number of electrons needed to fill their octet, the same number of valence electrons,
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
Boron has two few valence electrons to ever obtain a full octet.
