Key Stage 2
Meaning
Hydrogen is a gas that can catch fire easily.
Key Stage 3
Meaning
Hydrogen is a non-metal element with 1 proton in the nucleus.
About Hydrogen
- Hydrogen has the chemical formula H2.
- Hydrogen is a gas at room temperature.
- Hydrogen gas is less dense than air.
Testing for Hydrogen
- Collect the gas in a test tube.
- Place a lit splint over the mouth of the test tube.
- If a 'squeaky pop' sound is made then the gas is Hydrogen.
Key Stage 4
Meaning
Hydrogen is a non-metal element with 1 proton in the nucleus.
About Hydrogen
- Hydrogen has the chemical formula H2.
- Hydrogen is a gas at standard temperature and pressure.
- Hydrogen gas is less dense than air.
Isotopes
- Hydrogen has three common isotopes;
- Hydrogen – A stable isotope with no neutrons.
- Deuterium – A stable isotope with one neutron.
- Tritium – An unstable isotope with two neutrons.
