There are quite a few - actually any metal in Group 2A will have 2 valence electrons. Beryllium, magnesium, cadmium, and strontium are just a few of them.
Alkaline metals
fluorine
There are three electrons in boron's outer energy level.
Electrons are those found in the outermost energy level of an atom?They are called valence electrons.
Mercury has 80 electrons distributed in 6 energy levels,; namely:First Energy Level: 2Second Energy Level: 8Third Energy Level: 18Fourth Energy Level: 32Fifth Energy Level: 18Sixth Energy Level: 2Accordingly, Mercury has on the outer shell 2 electrons to share with in any chemical reaction by an ionic bond.
Outer energy level electrons, or valence electron.
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.

Alkali and alkaline earth metals
The alkaline earth metals (group 2 on the periodic table) have two valence electrons (electrons in their outer level).
Hydrogen, helium, alkali, alkaline metals.
The element magnesium has four electron energy levels and two electrons in its outer energy level in the neutral atom. Use the link to Wikipedia for more details.
