Key Stage 4
Meaning
Oxygen is a 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 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.
