Alkaline Earth Metals
Group contains: Metals
Electrons in the outer level: 2
Reactivity: Very reactive, but less reactive than alkali metals.
Other shared properties: Color of silver; higher densities than alkali metals.
They become increasingly soluble with a decrease in temperature. They are usually shiny and silvery, and are somewhat reactive at their normal pressure and temperature. They have low densities, and low melting and boiling points.
Because they are the 2nd most reactive group on the periodic table, the Alkaline Earth Metals are not found free in nature. They are named "alkaline" because when these compounds are mixed in solutions, they are likely to form solutions with a pH greater than 7, which are labeled as "basic" or "alkaline" solutions.
