Before you can build your model, you will need to know how many protons, neutrons and electrons your atom has. If you do not already know how to use the Periodic Table of Elements to find this information, read the 'How many protons, electrons and neutrons are in an atom of...?' page to learn how.

As you add electrons, protons and neutrons, the size of the atom increases. We can measure an atom's size in two ways: using the atomic number (Z) or using the atomic mass (A, also known as the mass number). The atomic number describes the number of protons in an atom.
