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.
- An atom of hydrogen has one electron.
- A Hydrogen ion has usually lost its only electron to become positively charged.
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
