5. What is an element?
All substances are made of very tiny particles called atoms.
There are about one hundred substances that are made up of just one type of atom. These are the elements.
carbon
helium
copper
The elements are the simplest substances in the universe.
The elements are the building blocks of all other substances.

6. Atoms in elements
An element is a substance made up of only one type of atom.
Copper is an
element made up of
copper atoms only.
Carbon is an
element made up of
carbon atoms only.
Helium is an
element made up of
helium atoms only.

7. Atoms and molecules of elements
An element is a substance made up of only one type of atom.
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.
Oxygen is an
element made up of
oxygen atoms only.
How many atoms
are there in an oxygen molecule?
Other elements, that contain atoms joined in molecules are hydrogen, nitrogen, chlorine and bromine.

8. You have been given a worksheet, in silence read the instructions
Let’s make an element
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!
