Key Stage 3

Meaning

An element is a material made of only one type of atom.

About Elements

There are over 100 different elements and they are all shown on the Periodic Table.
An element can be as little as one atom or could be trillions of identical atoms.
If there are any other types of atom in an object it is not an element.

Gold is an element made of Gold atoms. These lumps of Sulphur are made of only Sulphur atoms. This piece of Boron is made of only Boron atoms. A diamond is made of only Carbon atoms making it pure carbon.
Elements can be represented in a particle diagram by showing only one colour or shade to represent the atoms.

This is a solid element. An example would be gold. This is a liquid element. An example would be Mercury. This is a gaseous element. An example would be helium. This gaseous element is made of molecules of the element. An example would be oxygen.

Key Stage 4

Meaning

An element is a material made of atoms that all have the same atomic number.

About Elements

Atoms of the same element all have the same chemical properties.
There are several isotopes of each element which have slightly different physical properties such as density and melting point.
