Key Stage 2
Meaning
Key Stage 3
Meaning
Oxygen is a Group 6 non-metal element, on the Periodic Table, with an atomic number of 8.
About Oxygen
- Oxygen makes up 21% of the air.
- Oxygen has the chemical symbol O.
Molecular Structure
- The chemical formula for a Oxygen molecule is O2.
Atomic Structure
- Oxygen has 8 protons and 8 neutrons in its nucleus giving it an atomic number of 8 and a atomic mass of 16.
- Oxygen is in Period 2 of the Periodic Table because it has 2 electron shells.
Properties
- Oxygen is a gas at room temperature.
Key Stage 4
Meaning
Oxygen is a Group 6 non-metal element, on the Periodic Table, with 8 protons in the nucleus.
About Oxygen
- Oxygen makes up 21% of the air.
- Oxygen has the chemical symbol O.
Molecular Structure
- The chemical formula for an Oxygen molecule is O2.
- Oxygen forms a covalent bond with another Oxygen atom to produce a simple covalent molecule.
Atomic Structure
- The most common stable isotope of Oxygen has 8 neutrons in its nucleus giving it an atomic mass of 16.
- Oxygen is in Period 2 of the Periodic Table because it has 2 electron shells.
- Oxygen has 6 electrons in its outer shell and needs 2 more to get a full outer shell so it can form 2 bonds with other atoms.
Properties
Testing for Oxygen
- Collect the gas in a test tube.
- Place a glowing splint over the mouth of the test tube.
- If the splint relights then the gas is Oxygen.
