Group+02

 ​Mitchell C.

the group 2 in the periodic table of elements are all metals, (Beryllium, magnesium, calcium, strontium, barium, and radium.) They are all white and silvery.

**__ Beryllium __**: Symbol:Be, Atomic number:4, Atomic mass:9.0, isotope:Beryllium 9, Raw Color:White-Grey, Metallic The person that discovered this great object was a man named, Nicholas Louis Vauguelin in 1797, who lived in France. Beryllium later was found to be an element in 1828 by another man named Frederich Wobler, who lived in California.
 * Physical Properties:** Freezing Point: 1287°C Boiling Point: 2471°C beryllium has a high thermal conductivity and is nonmagnetic, it also has a small electric conductivity. state at room temperature:Solid, Density:1.85 grams per cubic centimeter, It is soluble only if it is crushed into a powder, beryllium exhibits extensive ductility near 700°C, and it is malleable but can withstand great force before bending. **Chemical Properties:** No reaction with air because of its thin layer of oxide that protects it. Non flammable, No general reactivity.
 * Fun Fact/s:** It provides the green color in emerald and blue aquamarine gemstones.
 * Uses:** Beryllium is used for windshield frames, brake discs, support beams, and other structural components of space[[image:howdy.jpg width="162" height="169" align="right" caption="magnesium electron configuration"]] shuttles.As well as florescent and electoral light bulbs.

__**Magnesium ** __:  Symbol:Mg, Atomic number:12, Atomic mass:24.3, Isotopes:magnesium 24 25 and 26, Raw Color:Silvery white, Solid This metal is the third most commonly used structural metal, following steel and aluminum. It was found by a farmer at Epsom in England during 1618, and was first produced in England by Sir Humphry Davy in 1808. mostly used for mostly vitamin supplements. **Chemical Properties:** **__ calcium: __** Symbol:Ca, Atomic number:20, Atomic mass:40.1**,** Isotopes:calcium 40 42 43 44, Raw Color: Dull Grey, Silver. calcium (a commonly used metal for vitamins and mineral supplements.) was known as early as the first century when the Ancient Romans prepared lime as calcium oxide. It was not isolated until 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide. Calcium metal was not available in large scale until the beginning of the 20th century. **Physical Properties:** Freezing Point: 727°C, Boiling Point: 1897 °C**,** Density: 4.5 g, Phase at room temperature: Solid. Used for fireworks, and glass making.
 * Physical Properties:**Freezing Point:649°C, Boiling Point:3600 °C, Density:108.6 lb, Phase at room temperature: Solid

Strontium: Symbol=Sr, Atomic number=38, Atomic mass=87.6, Isotope=strontium 86 Strontium is named after the Scottish village of Strontian, having been discovered in the ores taken from the lead mines. In 1790, Adair Crawford, a physician engaged in the preparation of barium, recognized that the Strontian ores exhibited different properties to those normally seen with other alkaline metals. So this new metal was called strontites in 1793 by Thomas Charles Hope, a professor of medicine at the University of Glasgow. He confirmed the earlier work of Crawford. He called it this from where it came from. This name was later changed to strontium by Sir Humphry Davy in 1808 by the electrolysis of a mixture containing strontium chloride and mercuric oxide, and announced by him in a lecture to the Royal Society on 30 June 1808. In keeping with the naming of other alkaline metals**Phase at room temperature: Solid Freezing Point: 769°C boiling Point: 1384°C** Raw Color: Silvery white metallic** The major use for strontium at present,is in producing glass for color television picture tubes.
 * Density: 2.54g

Barium: Symbol=Ba, Atomic number=56, Atomic mass=137.3, Isotope=barium 130 Barium was found in Greece, in which the Greek called it "Bary" meaning heavy. This was later changed to Barium after it was isolated by again Sir Humphry Davy. Freezing Point:727°C** Density:3.5 g Raw Color: Silvery White** uses for barium are, in X-ray diagnostic work, glass making, and rat poison.
 * Phase at room temperature: Solid
 * boiling Point:1640 °C

radium: Symbol=Ra, Atomic number=88, Atomic mass=226, isotope= radium 206 This is mostly used for medicine to fight off cancer of bone metastasis. But was founded by Marie Skłodowska-Curie and her husband Pierre. And was announced to the French Academy of Sciences on 26 December 1898. Unfortunately while experimenting with radio activity they died years later due to the after effects. Freezing Point:700.0 °C boiling Point:1737.0 °C ** **Density:5 grams Raw Color: Silvery White, Metallic** uses for radium are, Medicine and nuclear bombs.
 * Phase at room temperature:Solid
