Key Stage 3
Meaning
An electron is a small particle found orbiting the centre of an atom.
About Electrons
- Electrons negatively charged.
- In conductors electrons can pass easily from one atom to the next.
- When electrons move it is called an electrical current.
To see how electrons are arranged around the nucleus of atoms or to see how electrons move around a circuit click on the pictures below to play a PHET simulation.
Key Stage 4
Meaning
The Electron is a negatively charged particle found orbit the nucleus of an atom in electron shells.
About Electrons
- Electrons have a relative atomic charge of -1 and a relative atomic mass of 1/1860.
- The electrons and their shells are responsible for the chemistry of an atom.
- When atoms bond to form molecules some atoms can share their electrons forming a Covalent Bond, some transfer an electron from one atom to another forming an Ionic Bond while others allow electrons to pass freely between many atoms forming a Metallic Bond.
