Resource summary

Chemistry
  1. Chemical Changes and Structure
    1. Atomic Structure
      1. Proton- Location=nucleus, Mass=1, Charge=+1
        1. Neutron- Location=nucleus, Mass=1, Charge=0
          1. Electron- Location=shell, Mass=almost 0, Charge=-1
        2. Mass Number= Protons+Neutrons
          1. Electron Arrangement
            1. First Orbital can hold ONLY 2 electrons
              1. Second Orbital can hold ONLY 8 electrons
                1. Third Orbital can hold ONLY 8 electrons
          2. Bonding and Properties
            1. Atoms from bond to acheive chemical stability
              1. 3 types of bonding: Covalent, Ionic and Metallic
                1. A Covalent Bond is when two non-metal atoms join together and share electrons
            2. Acids and Bases
              1. The pH scale
                1. 1-6 is stronger acids
                  1. 8-14 is stronger alkalis
                    1. 7 is neutral solution
                2. Ionic Formulae
                  1. Ionic formulae shows the charges on ions present in ionic compounds. It can be written for compounds containing metals and non-metals and non-metals and ammonium compounds.
                  2. Concentration and the Mole
