What is an Atom?

Atoms are like tiny Lego building blocks. 

Everything in the world is made of them.

Your toys, your bed, and even YOU, are all made up of atoms. But they are just so tiny you can't see them.

The Structure of Atom

Three subatomic particles -

Proton: These are tiny parts with positive energy. They stay in the middle of the atom

Neutrons - These are quiet parts that have no energy at all, stay in the middle to keep company for protons.

Electron - These parts are tiny but fast they like to buzz around with a negative part. They zoom around the outside of the atom.

Two main parts of the atom

The nucleus is where the protons and neutrons live. 

The cloud of electrons is where the electrons live. Always buzzing with energy.
