About Fluorine
Molecular Structure
- Fluorine has the chemical formula F2.
Atomic Structure
- Fluorine as 9 protons and 10 neutrons in its nucleus giving it an Atomic Number of 9 and an atomic mass of 19.
- An atom of Fluorine is missing one electron from having a full outer shell.
Properties
- Fluorine is a non-metal element.
- Fluorine is the most reactive Halogen.
- Fluorine reacts strongly with Hydrogen to produce Hydrogen Fluoride which dissolves in water to produce Hydrofluoric Acid.
- Fluorine is a strong bleaching agent.
- Fluorine kills bacteria.
- Fluorine is a yellow coloured gas at room temperature.

Properties
- Fluorine is a non-metal element.
- Fluorine is the most reactive Halogen.
- Fluorine reacts strongly with Hydrogen to produce Hydrogen Fluoride which dissolves in water to produce Hydrofluoric Acid.
- Fluorine is a strong bleaching agent.
- Fluorine kills bacteria.
- Fluorine is a yellow coloured gas at standard temperature and pressure.
Testing For Fluorine
- Collect the gas in a test tube.
- Place a piece of litmus paper over the mouth of the test tube.
- If the litmus paper is bleached white then the gas is Fluorine or Chlorine.
