Electrons in the outermost shell are valence electrons!
Helium has two valence electrons in the 1s orbital.
shared between the atoms or transferred from one atom to another to form chemical bonds.
Ionic bonds deal with the transfer of valence electrons from one atom to another. These are the outermost electrons in an atom's electron cloud.

Electrons in the outermost shell are valence electrons!
the electrons in the outermost shell of an atom are considered to be the valence electrons.
helium has only one shell with two electrons and can be considered to be as the valence electrons.
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).

Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
Helium has two valence electrons in the 1s orbital.

The number of electrons are different from one to another, however all of them have seven electrons in the valence shell.
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.
