Image result for periodic table groups
  • Energy is made of different wavelengths.  Radio waves have the longest wavelength.  Gamma rays have the shortest.  Visible light has medium wavelength. 
Image result for electromagnetic spectrum
  • Atoms are made of protons, neutrons, and electrons. 
  • Protons and neutrons make up the nucleus of the atom.
  • The type of atom is determined by the number of protons in the nucleus.
  • The Periodic Table organizes all of the types of atoms (elements) into periods and groups that share properties.
  • Know where the Noble Gases are. Noble gases don't react with other elements.
  • Know where the Halogens and Alkali Metals are. They are very reactive with other elements and combine easily to make compounds.
  • Elements are substances that are made of only one type of atom. For example: all the types of atoms in the periodic table, like Hydrogen, Helium, Lithium, Oxygen, Gold, Silver
  • Compounds are made of more than one atom.  For example: Water and hydrogen peroxide
