Name and symbol Name: Beryllium Symbol: Be Symbol
Atomic Number and Mass Atomic Number: 4 Atomic Mass: with 9 isotopes Atomic Number Atomic Mass
Group- Metals, Nonmetals, Metalloids? Beryllium is a metal Found in group 2 It is Alkali-Earth Metal
History Discovered by Louis-Nicholas Vauquelin in 1798 Etymological origin of name: Greek: beryllos, beryl Element symbol comes from the first two letters of the element!
Compounds Where it Commonly Exists One compound is Beryllium dihydride (BeH 2 ). It appers as a solid,and it is white. Its density is 650 kg m-3. Another compound is Beryllium Oxide (BeO 3 ). It is a crystalline solid. Its density is 3010 kg m-3. Beryllium Oxide
Uses Beryllium, unlike other metals, is virtually transparent to x-rays. So, it is used in radiation windows for x-ray tubes. Beryllium alloys are also used for aircraft, satellites and spacecraft because they require light-weight materials. Another use of Beryllium is that it used in nuclear reactors.
Found Beryllium is not found pure in nature, but beryllium compounds can be found in different mineral rocks, soil, coal, oil, and volcanic dust.
Where is it found? Can be found almost anywhere in the world, but it is not found in its pure form. Found in Emeralds and other gems. It is natural.
Physical Properties Melting Point- 1278°C (2,349°F) Highest melting point of the light metals Boiling Point- 2,500°C (4,500°F) Density-1.8 grams per cubic centimeter High heat capacity and high heat conductivity
State of Matter solid At room temperature, Beryllium is found as a solid
Chemical Properties Beryllium reacts with acids. Beryllium also reacts with different halogens. Beryllium does not react with water or steam.
Additional Facts Beryllium can be extremely harmful to your health when breathed in. Beryllium salts are very toxic.
