Unit 3: Atoms, Molecules & Ions
Key Learning Targets
(3.01) Discuss some historical events that lead to Dalton’s proposal of his atomic theory.
(3.02) Describe the basic postulates of Dalton’s Atomic Theory.
(3.03) Describe the key historical discoveries of J.J. Thomson, Millikan, Rutherford, and Chadwick that led to the discovery of the structure of the atom.
(3.04) Describe the structure of the atom in terms of protons, neutrons, and electrons and list the relative charge, mass, and location of these particles.
(3.05) Calculate average atomic mass from natural abundance of isotopes and masses of individual atoms.
(3.06) Explain how ions are formed, determine the number of electrons gained or lost based on ionic charge and use the periodic table to predict charges of ions.
