Their valence shells are completely full, so they are least likely to be reactive and are thus most stable.
the noble gases
Gases with eight valence electrons.
Noble Gases
The noble gases (aka inert gases) are the most stable elements.
Because fluorine is having the most electronegativity and is the most reactive non metal.
the most stable element group is the noble gases group
Noble gases are stable in nature. They are placed in group-18.
Noble gases have completely filled outer most shell and have stable electronic configuration. They are chemically inert and exist as monoatomic species.
Elements in the most stable group of the periodic table, also known as the noble gases, have full outer shells. This means they have 2 electrons in the case of helium, and 8 electrons for all other noble gases.
Noble gases have a full outer shell of electrons, making them stable and non-reactive. Their electron configuration is already at its most stable state, so they do not easily form bonds with other elements. This is why noble gases are often called inert gases.
Being extremely stable. Noble gases have full valence shells.
They are stable.
