Atoms

Particles all have different charges

- protons have a charge of +1

- neutrons have a charge of 0

- electrons have a charge of -1

Things to remember;

- number of protons = number of electrons

- the atomic number (bottom number) tells you how many protons there are

- The mass number (top number) tells you the total number of protons and neutrons
