10The K-shell can hold a maximum of two electrons.
Helium has two shells.
The formula 2n² is used to find the maximum number of electrons in a shell.
Helium is chemically inert due to duplet state.
Octet state means having 2 electrons in the outermost shell.
Inert gases have 8 electrons in their valence shell (except helium).
Atoms gain, lose or share electrons to become stable.
The outermost shell is called valence shell.
Sodium has one valence electron.
Chlorine has 2 valence electrons.
