valence shell
The valence shell is the outermost shell of the atom. For example, hydrogen (which is located on Period 1) has only one shell and it is its valence shell. Another example, bromine (which is located on Period 4) has four electron shells, and its fourth shell (counting away from the nucleus) is its valence shell containing seven electrons.
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.

Krypton is a noble gas; it has 8 electrons in its valence shell.
valence shell
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
This valence shell has the valence electrons.
The outer shell is called the valence shell
The outermost energy level of an atom is referred to as the valence shell.
These are the noble gases which have a complete valence shell.
Valence shell comprises of electrons. These are used in bonding.
