Boron

Boron is a chemical element with the symbol B and atomic number 5. It is a metalloid, meaning it has properties of both metals and nonmetals. Boron is a relatively rare element in the Earth’s crust, but it has many important uses in industry, medicine, and science.

Atomic Number	5
Electron Configuration
Electrons Per Shell	2-3

Crystal Structure: Simple Trigonal

Space Group Number: 166

One of the most interesting things about boron is its ability to form strong, covalent bonds with other elements. Boron’s electron configuration allows it to form three covalent bonds, which means that boron compounds tend to have very high melting and boiling points. This property makes boron useful in high-temperature applications such as rocket engines and nuclear reactors.

Another important use for boron is as a dopant in semiconductors. By adding small amounts of boron to silicon, engineers can create p-type semiconductors that have a positive charge. This is important for making transistors and other electronic devices.
