Atoms and Elements

Atoms
Atoms are the building blocks of all matter and
are the simplest form of molecule. They are all
made up of protons, neutrons and electrons. They
look something like this
The Nucleus this contains neutrons and protons
Electrons these orbit around the nucleus
3
Elements
If a solid, liquid or gas is made up of only one
type of atom we say it is an element. For
example, consider a tripod made up of iron

Compounds
Compounds are different to elements. They
contain different atoms. Here are some examples
