ATOMS

ATOMS

1. DALTONS THEORY

   • All matter is made up of atoms
   • Same atoms make up element
   • 2 or more different atoms combine to form compounds
   • Chemical Reaction causes
     • Rearrangement
     • Seperation
     • Combination

2. Composed of Subatomic particles

   • Protons
     • Always have the same #
     • +, Heaviest
   • Neutron
     • 0, Heaviest
   • Protons and electrons inside

3. Atomic #

   • # of Protons
   • #of Electrons

4. Atomic Mass

   • Protons + Neutrons
