Key Stage 2

Meaning

Oxygen is a gas in the air.

Key Stage 3

Meaning

Oxygen is a 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

Oxygen has 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 non-metal element, on the Periodic Table, with 8 protons in the nucleus.

About Nitrogen

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 atoms 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

Oxygen is gas at standard temperature and pressure.

Testing for Oxygen

  1. Collect the gas in a test tube.
  2. Place a glowing splint over the mouth of the test tube.
  3. If the splint relights then the gas is Oxygen.
