What is Matter? By Juan castillo

Matter is classified as a Pure Substance or Mixture

Pure Substances

Pure substances: substances that are made up of one only type of atom

Like Gold

Compound: a Pure Substance composed of two or more different atoms chemically bonded to one another

Like Salt

Element: a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number


Mixtures: a combination of two or more pure substances

There are two types of Mixtures

Homogeneous & Heterogeneous

Like Coke
