Examples
- Caesium is a highly reactive metal that readily loses one electron to form a positive ion.
- The most common application of caesium is in atomic clocks, which use the element's precise vibrations to regulate time.
- Due to its high reactivity, caesium is typically stored in mineral oil to prevent it from coming into contact with air.
- Caesium has a melting point of just 28 degrees Celsius, making it one of the few metals that is liquid at room temperature.
- The name caesium comes from the Latin word for blue, referring to the bright blue lines that appear in the element's atomic spectrum.
