- Chantelle Beeter GROUP 2 Characteristics Beryllium - Do not occur naturally as free elements
- occur most commonly as the carbonates, phosphates, silicates, and sulfates
- occur naturally as compounds that are either insoluble or slightly soluble in water
- Usually form ionic compounds
- two valence electrons REFRENCES:

. Beryllium Strontium Magnesium Calcium Barium Radium Uses Magnesium is used in flares. Fireworks: Barium is the green sparks.
Strontium is the red sparks. The Body:
Calcium found in bones and teeth.
Magnesium helps absorb the calcium. Magnesium is used in tracer bullets. Barium is used in X-Rays. Magnesium is found in chlorophyll, the greenish pigment in plants. Cautions Beryllium is a known human carcinogen. Calcium reacts violently with water; producing hydrogen gas. Properties -Readily lose their valence electrons to form cations. - good heat and electrical conductors -Reactive, but less reactive than alkali metals -High melting point -High boiling point - ductile & malleable - low electronegativty. Barium is used as a colorant in red lipsticks and cosmetics Sarquis, M., & Sarquis, J. L. (Eds.). (2012). Modern Chemistry. Orlando, FL: Houghton Mifflin Harcourt. - react with nonmetals, in particular halogens. Barium powder can ignite spontaneously in air. alkaline-earth metal. (2012).
