Valence electrons are those that exist in the highest main energy level in the last shell of an atom.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
I believe there is 8 electrons in the outer valence
The outermost electrons in an atom are called Valence electrons.
Calcium's atomic number is 20. It therefore has 20 protons and 20 electrons. Since calcium is a group 2 element, 2 of those electrons are valence electrons.
3 electrons !
Valence electrons are those that are in the outermost shell of the atom.
The valence electrons are the outermost electrons, i.e. those that reside in the outermost energy level.
Those are called Valence Electrons.
Those electrons are the valence electrons. They are the electrons which mostly take part in exchange of electrons or sharing of electrons. Hence, valence shell electrons are a very important part of chemistry since all the reactions due to them only.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
The outermost electrons in an atom that are responsible for all chemistry are known as valence electrons.

Valence electrons
the electrons in the outermost shell of an atom are considered to be the valence electrons.
