What are atoms, molecules, elements, isotopes, and compounds and what makes them different from each other.

**Atoms-** //Atoms are the main building block of all matter. Atoms make up all elements. The atom has three main structures, electrons, neutrons, and protons.//

**Elements-** //Elements are chemical substances that can't be broken down in to any smaller form using chemical or heat treatment. The Periodic Table helps organize and group the elements.//

**Isotopes-** //Elements with a different number of neutrons but the same number of protons are called Isotopes. Because of the different amount of Neutrons, the atomic mass is different.//

**Molecules-** //A group of atoms that have specific properties and structures are called a molecule. Molecules are one of the smallest forms of a substance, along with atoms.//

**Compounds-** //When two or more elements are bonded together it forms a compound. There are two main types of bonds, Ionic bonds and Covalent bonds. Ionic bonds are when one atom donates electrons to another. Covalent bonds are when the electrons are shared with the atom.//
