C2_atoms + the atomic structure
  1. contents of an atom.
    1. electrons
      1. mass= 0.0005
        1. charge= -1
        2. protons
          1. mass= 1
            1. charge = +1
            2. neutrons
              1. mass = 1
                1. charge= 0
                  1. mass number - atomic number.
                2. electronic congifuration
                  1. the first shell has 2 electrons
                    1. the other shells have a maximum of 8.
                      1. e.g. carbon. = 2, 4
                  2. atoms are the smallest particle of an element.
                      1. atomic number = no.protons=electron
                        1. mass number = no. neutrons + protons.
                          1. always bigger+untop
                        2. Ions.
                          1. when an atom loses or gains electrons.
                            1. lose electron, more protons, positive charge
                              1. gain electron, more electrons, negative charge
                                1. eg. ^19F-
                                  1. fluoride= p; 9, n;10 e; (plus one, it had a minus one) 10
                                2. isotopes
                                  1. different number of neutrons.
                                    1. same electrons and protons
                                  2. contributions.
                                    1. john dalton
                                      1. ~all matter is made up of atoms
                                        1. ~discovered atoms
                                        2. Joseph Thompson
                                          1. ~found the sub-atomic particle, electron
                                          2. Earnest Rutherford
                                            1. ~nucleus is positively charged
                                              1. ~discovered second aub-atomic particles
                                              2. Niels Bohr
                                                1. ~discovered the outer shells
                                                  1. ~found out electrons spiral inwards
