Valence shell
Valence shell
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Electrons in the outer most shell are called Valence Electrons.
Valence shell and Ultimate Shell
The outer most electron shell of iodine atom contains 7 electrons.

Valence electrons
The outer shell of an atom is the valence shell, which contains the valence electrons.
An oxygen atom has six (6) electrons in its outer shell.
An atom is most stable and unreactive when it has eight electrons in its outer shell, a configuration known as the octet rule. This is because having a full outer shell typically leads to lower energy and greater stability. However, helium is an exception, as it is stable with just two electrons in its outer shell.
It becomes a cation
