Chem 103 Module 2 Elaborate Exam Study Questions with 100% Correct Answers | Latest Edition 1. Uncertainty Principle - ANSWER - Position and momentum of an electron cannot be looked at at the same time and know both values with certainty - Comes from uncertainty of math - Werner Heisenberg 2. Wave equation - ANSWER - Erwin Schrödinger - Mathematical expression used to give a three-dimensional map of where an electron is most probably located in the atom: orbital - Reproduces Bohr's expression for the energy not only for hydrogen but for all atoms - Describes the location, energy, and properties of electrons 3. Principle Quantum Number - ANSWER - Shell - 'n' - Energy level - Specifies the size of the orbital - n= 1 to infinity 4. Waves - ANSWER Oscillation or periodic movement that can transport energy from one point space to another 5. Electromagnetic Waves - ANSWER Consist of an electric and magnetic field, oscillating perpendicular to one another as well as the direction of travel 6. Wavelength - ANSWER - Distance between two consecutive peaks or troughs in a wave - Measured in meters 7. Frequency - ANSWER - Number of wave cycles (complete wavelengths) that pass a specified point in space in a specified amount of time - Measured in hertz, Hz (cycles per second, 1/s or s^-1) 8. Amplitude - ANSWER Magnitude of the wave's displacement, which is one half the height between the peaks and troughs 9. Electromagnetic Spectrum - ANSWER Range of energies that electromagnetic radiation can comprise, including radio, microwaves, infrared, visible, ultraviolet, x-rays and gamma rays 10. Isaac Newton - ANSWER When trying to separate the colors of light it went in a straight line the way particles do so light was made of particles 11. Christian Huygens - ANSWER Reflection and refraction leading him to saying light was waves 12. Thomas Young - ANSWER - Double slit experiment - Light shown through both slits should have appeared as two line of viewing screen but instead their were multiple lines showing that Light was made of waves 13. James Clerk Maxwell - ANSWER - Light is made of two waves; electric and magnetic field - First colored photo 14. Two Domains Scientists View the Physical Universe as - ANSWER - Matter - Electromagnetic Radiation 15. Acetate - ANSWER CH3COO- 16. Cyanide - ANSWER CN- 17. Carbonate - ANSWER CO3 2- 18. Nitrate - ANSWER NO3- 19. Nitrite - ANSWER NO2- 20. Sulfate - ANSWER SO4 2- 21. Sulfite - ANSWER SO3 2- 22. Phosphate - ANSWER PO4 3- 23. Possible Combinations of Ions in an Ionic Compound - ANSWER Cation Anion Monatomic Monatomic Monatomic Polyatomic Polyatomic (NH4+) Monatomic Polyatomic (NH4+) Polyatomic 24. Covalent Compounds - ANSWER - Molecular compounds - Form when atoms of 2 or more elements share rather than transfer (gain or lose) electrons - Discrete, neutral molecules - Nonmetal + Nonmetal(s) - Gases - Low boiling point liquids - Low melting point solids 25. Matter - ANSWER Composed of particles moving according to Newton's laws of motion 26. Electromagnetic Radiation - ANSWER - Consists of waves governed by Maxwell's equations - Paradoxes prevented full explanation under either framework 27. Wave Particle Duality - ANSWER Observation that elementary particles can exhibit both wave-like and particle-like properties 28. Black Body Radiation - ANSWER - Appear black because they absorb all wavelengths of light and emit energy when heated - When it emits light when in the visible range it shows the temp 29. UV Catastrophe - ANSWER Inability to see energy emitted by black body radiation
