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.
There are three electrons in boron's outer energy level.
Metals can conduct energy because their outer electrons are free to move and carry electric charge through the material. This movement of electrons allows for the flow of electricity and heat to easily travel through the metal.
The reactivity of an atom is due to its number and arrangement of __________ in the outer energy level (or orbit). your question was confusing but I was able to interperet it. the answer is Electrons
Electrons found in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms, which determines the atom's reactivity and behavior in chemical reactions. The number of valence electrons an atom has contributes to its position in the periodic table and helps predict its chemical properties.
Atoms of elements in Group 7A of the periodic table, also known as Group 17 or the halogens, have 7 electrons in their outer energy level. Examples of elements in this group include fluorine, chlorine, bromine, iodine, and astatine.
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.
One
They are called Alkaline Earth Metals
Cause they W
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
Uranium has 2 electrons on its outer energy level.
Hydrogen, helium, alkali, alkaline metals.
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.
