Unformatted text preview: Exam I Review Sheet: Chapter 1: • Know the elements on the “full periodic table” found under ‘Handouts’ on my web‐page. ‐ The elements NOT shaded are the ones you need to know. Make sure to know there oxidation numbers if they have one. • Be able to identify type of element, (i.e. Alkali metal, transition metal, halogen, and etc…) • Know the following definitions: ‐ Intensive property ‐ Extensive property ‐ Physical property and change (be able to identify) ‐ Chemical Property and change (be able to identify) ‐ Accuracy ‐ Precision • Know the SI units for the following measurements: ‐ Mass ‐ Volume ‐ Pressure ‐ Temperature • Know the following equations and conversions: ‐ 1cc = 1mL ‐ 2.54cm = 1 in ‐ Metric conversions ‐ °C to Kelvin ‐ Density Chapter 2: • Know the following laws: ‐ Law of Conservation of Mass ‐ Law of Definite Proportions ‐ Law of Multiple proportions • Know Dalton’s Atomic theory – what were his 4 postulates? (don’t have to completely memorize, but roughly what they are) • What did the following experiments discover? ‐ Cathode Ray Tubes ‐ Oil Drop Experiment ‐ Gold Foil Experiment • Be able to define and determine the number of electrons, protons, and neutrons: ‐ Isotope ‐ Ion • be able to calculate the atomic mass of an element given the masses and percent abundance of its isotopes. • Know the following definitions and be able to identify: ‐ Atom ‐ Element ‐ Molecule ‐ Compound o Covalent o Ionic ‐ Pure substance ‐ Mixture o Homogeneous o Heterogeneous Chapter 5: • Know how and when to use the following equations (need not memorize them, they are on the back of the periodic table I handed out in class and on the periodic table you will have for the exam) ‐ ‐ (1 photon) ‐ λparticle h mv “De Broglie wavelength” • How were the original and current day periodic tables arranged? Ans: atomic mass & atomic number • Know the two components of light – electric and magnetic • Know the following: ‐ Wavelength ‐ Frequency ‐ Amplitude • What is the EM Spectrum? • What is an Atomic Spectra? • Know the following definitions: ‐ Blackbody radiation ‐ Photoelectric effect ‐ Diffraction ‐ Refraction ‐ Wave‐particle duality ‐ Heisenberg uncertainty principle ‐ Valence electrons ‐ Aufbau principle ‐ Hund’s Rule ‐ Pauli exclusion principle • What was Bohr’s model of the atom?
