  • How is a mixture different from a compound?
    A mixture does not create a new substance, each element keeps their original properties. A compound creates a new substance from two other substances.

    Non-metals
  • The basic unit of a chemical element, that is made up of protons, electrons, and neutrons.
    Atom
  • An elementary particle having no charge and equal mass to a proton, found in the nucleus of all atoms except Hydrogen.
    Neutron
  • A positively charged particle, that exists dependently within the nucleus of an atom. 
    Proton
