Examples of Chemical Reactions With a Non-Metal
Gallium nitride is formed when gallium chemically reacts with nitrogen (N). A crystal is formed, which allows it to have many applications. For example, the compound is used to read Blu-ray Discs.
- Some alloys are used in thermometers to replace mercury.
- Its' name comes from the Latin word "gallia", meaning France.
- It is used to produce blue or violet LED's.
- The element has to be extracted in trace amounts from other elements since it doesn't occur naturally on it's own.
- Ions of gallium can be used as antibiotics.
- A gram of gallium can be bought for $3.
- Gallium is widely used in many electronics.
- Gallium is used in nuclear weapons. It is combined with plutonium because it stabilizes the plutonium and protects the plutonium from corrosion.
