background image Chemistry Test 1- What to Study based on the homework problems we’ve been given  Chapters E,1, and 2 EQUATIONS AND CONSTANTS- Dr. Clark told me we did not have to memorize 
equations and constants, just that we need to recognize how and when to use
them
We do need to be able to recognize elements by their atomic symbols Review Practice problems from the end of chapters (odd number questions 
include the answers)
Notes for Chapters 1 and 2 are uploaded already, review those for more 
depth into each topic
CHAPTER E Scientific Notation o Rules for addition and subtraction
o Rules for multiplication and division
Prefix Multipliers Significant Figures o Rules for addition and subtraction
o Rules for multiplication and division
Dimensional Analysis (converting units) CHAPTER 1 States of matter o Solid
o Liquid
o Gas
Pure Substance vs. Mixture o Element vs. Compound
o Heterogeneous vs. homogeneous
The Scientific Method Law of Conservation of Matter Theory vs. Law Early vs. Modern Atomic Theory Law of Conservation of Mass Law of multiple proportions Definition of Modern atomic theory JJ Thompson’s cathode ray experiment Properties of electrical charge Plum pudding model of electron (incorrect model) o Disproved by Rutherford’s gold foil experiment
o Be familiar with Rutherford’s more correct atomic model
Radioactivity NUCLEAR THEORY Subatomic units and their relative charged (e-, p+, n0)
background image BE ABLE TO RECOGNIZE ATOMIC SYMBOLS ON PERIODIC TABLE Atomic number, mass number and isotopes Ions, cations, and anions Atomic mass and mass spectrometry Moles and molar mass CHAPTER 2 Quantum mechanics developed to explain the behavior of subatomic particles Wavelength- distance from trough to trough or crest to crest of one wave (in 
nm)
Frequency- how many waves pass through a point in one second (measures 
in Hertz/Hz)
Symbols for frequency and wavelength Frequency and wavelength are inversely proportional Be familiar with the electromagnetic spectrum Speed of light = wavelength x frequency Emission spectrum, atomic spectroscopy, identification of atoms Rydberg equation Bohr Model of atom Wave nature of electron De Broglie relation o Wavelength=h/(mv) Uncertainty Principle- cannot observe wave and particle nature of light 
simultaneously
Heisenberg’s Uncertainty Principle  Probability distribution map and indeterminacy E=hv Wave-particle duality of light  Solutions to the Schrodinger o Quantum numbers and their shapes N- principal quantum number Higher n= higher energy l- angular momentum quantum # l= 0 through -1 know difference between s,p,d,f m sub-l- magnetic quantum # values of ml are -l through +l m sub-s- spin quantum # +1/2 or -1/2 o Principal level- group of orbitals with same n value
o Sublevel- group of orbitals with same n and l value
o Change in Energy between orbitals = -2.18x10^-18 J [(1/n final)-(1/n 
initial)] Radial distribution function o Total probability of finding e- a certain distance from nucleus=
