Key Stage 2
Meaning
Key Stage 3
Meaning
Fluorine is a Group 7 element, on the Periodic Table, with an atomic number of 9.
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.
- Fluoride ions gain 1 electron to get a full outer shell and become negatively charged.
Properties
- 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.

Atomic Structure
- The most stable isotope of Fluorine has 10 neutrons in its nucleus giving it an atomic mass of 19.
- An atom of Fluorine is missing one electron from having a full outer shell.
- Fluoride ions gain 1 electron to get a full outer shell and become negatively charged.
Properties
- 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.
