Alkali Earth Metal
Beryllium/4/metal/alkali earth metal. Beryllium in greek means beryl. Being steel gray in color has many desirable properties. It is one of the lightest metals. It has the highest melting point, resists nitric acid attacks, excellent thermal conductor (absorbs heat), and is not magnetic. In ordinary temperature it resists oxidation (rusting) in air. Beryllium mixed with Copper/29/metal makes Beryllium Copper which is used to make springs, electrical contacts, spot-welding, communicational satellites, non sparking tools, high speed air crafts, missiles, spacecrafts, windshield frames, brake discs (car breakers), and support beams.
~Magnesium/12/metal/Alkali Earth Metals. It is the eighth most abundant element in the crust. It never appears naturally uncombined. It is produced by electrolyzing magnesium-chloride. It ignites easily in air and burns with a white flame. It is used for are; flashlight photography, flairs, and pyrotechnics.
~Calcium/20/metal/Alkali Earth Metals. In Latin it means lime. Lime was prepared by the Romans in the first century under the name Calx. It was first prepared by electrolyzing lime in Mercury/80/metal. It is the fifth abundant element on Earth. It forms 3% of the crust. It is found in leaves, bones, teeth, and shells
.~Strontium/38/metal/Alkali Earth Metal. It is named after Strontain, a town in Scotland. It is formed by electrolyzing KCl( Potassium/19/metal/Alkali Metal + Chlorine/17/nonmetal/Halogen). It ignites spontaneously and produces colorful sparks so it is used in pyrotechnics.
~Barium/56/metal/Alkali Earth Metal. In Greek it means heavy. It is made by the electrolyzing of Chlorine/17/metal/Halogen. It oxidizes easily, so it has to be kept in oxygen free liquids
.~Radium/88/metal/ Alkali Earth Metal. In Latin it means ray. This was discovered by Marie Curie. This is present in all Uranium/92/metal/Actinia Series minerals. It also decomposes in water. It decomposes into Alpha, Beta, and Gamma rays which if it hits other atoms will disintegrate into Alpha, Beta, and Gamma rays.
