What is an element?

All substances are made of very tiny particles called atoms.

The elements are the simplest substances in the universe.

The elements are the building blocks of all other substances.

copper

carbon

There are about one hundred substances that are made up of just one type of atom. These are the elements.

helium

An element is a substance made up of only one type of atom. Atoms in elements

Copper is an element made up of copper atoms only.

Carbon is an element made up ofcarbon atoms only.

Helium is an element made up ofhelium atoms only.

Atoms and molecules of elements

In some elements, the atoms are joined in groups of two or more. A

particle containing atoms grouped in this way is called a molecule.

An element is a substance made up of only one type of atom.

Other elements, that contain atoms joined in molecules are hydrogen, nitrogen, chlorine and bromine.

Oxygen is an element made up of oxygen atoms only.

How many atoms are there in an oxygen

molecule?

Let’s make an element

1. You have been given a worksheet, in silence read the instructions

2. Pick one element which you will make

3. Start making your element !

Every element is different- it has a different number of electrons and protons!
