Noun
valence shell (plural valence shells)
(chemistry) the outermost shell of electrons in an atom; these valence electrons take part in bonding with other atoms
It is inert to most common chemical reactions, such as combustion, because the outer valence shell contains eight electrons. Source: Internet

Since the electrons added fill the (n-1)d orbitals, the properties of the d-block elements are quite different from those of s and p block elements in which the filling occurs either in s or in p-orbitals of the valence shell. Source: Internet
The valence shell has eighteen electrons – ten more than the eight found in the valence shells of the noble gases from neon onward. Source: Internet
This is caused by the filling of the valence shell of the atom; a group 17 atom releases more energy than a group 1 atom on gaining an electron because it obtains a filled valence shell and is therefore more stable. Source: Internet
