The Periodic Table

What Are Elements Made of? If we broke down an element into a single particle it would be called an atom. Atoms are made of three different kinds of subatomic particles. -Protons = positively charged particle -Neutrons = neutral particle -Electrons = negatively charged particle

Structure of an atom? Where are the subatomic particles found in an atom? Subatomic particle Placement in atom ProtonsFound in the center NeutronsFound in the center ElectronsFound circling the outside

Structure of an atom.

Where can we find information on the number of subatomic particles for different types of atoms? Use the periodic table

..
