They are called Alkaline Earth Metals
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.

You think probable to alkali earth metals.
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
The alkaline earth metals (group 2 on the periodic table) have two valence electrons (electrons in their outer level).
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
Hydrogen, helium, alkali, alkaline metals.
Uranium has 2 electrons on its outer energy level.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
The family of elements with two electrons in its outer energy level is the alkaline earth metals. This group includes elements like beryllium, magnesium, calcium, strontium, and barium. These elements are highly reactive and tend to form 2+ cations by losing their two outer electrons.
Vanadium has 5 electrons in its outer energy level.
