- Use Significant Figures, scientific notation, and SI units in calculations
- Take measurements with accuracy and precision
- Use Dimensional Analysis in calculations
- Distinguish among elements, compounds and mixtures
- Classify matter as pure substances or mixtures through investigation of their properties
- Understand the experimental design and conclusions used in the development of modern atomic theory, including Dalton's Postulates, Thomson's discovery of electron properties, Rutherford's nuclear atom and Bohr's nuclear atom
- Describe the structure of an atom in terms of protons, neutrons and electrons
- Use isotopic composition to calculate average atomic mass of an element
