Beryllium Facts!
{ Below} emerald jewlery being shown on a stand
Beryllium is the 4th element of the table.
Name: beryllium
Chemical symbol: Be
Atomic #: 4
atomic mass: 9.01
state of matter: solid
Color of it's pure state: lead gray
element group name: metal
Number of Protons and Electrons:4
Number of Neutrons: 5
Is it radioactive? YES
Is it harmful to your body? YES
Description:
The pure form of Beryllium is solid.
Beryllium looks like a shiny, bumpy piece of coal.
Research Questions
Scientist Louis Vauquilen discovered the element beryllium.He discovered it in 1797 while looking at emeralds and beryl. Thinking he was only checking out the qualities of the emeralds and beryl for his scientist friend René Haüy , He would have never thought to discover a brand new element: Beryllium!
Beryllium is used in :
weight metal alloys*,
x ray tube windows,
watch springs,
sparkless tools,
missiles,
space craft,
air craft,
and electrical contacts*.
*Contacts are junctions of electric conductors, usually metal, that controls current flow.
*alloys are a substance made of 2 or more metals.
*conductors are substances that allow electricity to flow through, unlike insulators.
Why is beryllium used in electrical contacts and missles?
Beryllium oxide is an electrical insulator and thermal conductor*, so it can be used in wires and electrical contacts. People use beryllium oxide for ceramics. Beryllium oxide is a white, crystalline oxide. In other words, it's when beryllium is turned into a gas. The beryllium oxide holds in heat , so it is used in nuclear applications such as the
neutrons reflector, etc.{ Beryllium fluoride was used in the Molten Salt Reactor Experiment.}
beryllium's Half Life* Is 1.51 million years! WOW!
*Half Life: the time needed for something to fall to half of it's initial value.
Fun facts!
1] Beryllium's salts are really sweet, but toxic and harmful to your body. That was found out the hard way.
2] It's the lightest alkaline metal from earth.
3] It has one of the highest melting points.: 1278.0 celcius]
4]the molten salt Reactor experiment was an experimental molten-salt nuclear reactor done at the Oak Ridge National Laboratory in 1964.The scientists realized that molten salt of the element beryllium could be used in bombs and missles.
