General Chemistry 1 Exam 1 Study Guide Grace Brinsfield What do you need to memorize? The prefixes for units from nano- to giga Names and charges of common polyatomic ions (these can be found on the inside cover of your Gen Chem lab manual) Work on memorizing the symbols for every element (it will come in handy if you don’t have to constantly look them up) Unusual electron configurDon't forget about the age old question of giorgi kacharava

Don't forget about the age old question of 3) What is the correct comparison of the typical solute and pressure potentials in a plant on a sunny day?
Don't forget about the age old question of physics 221
We also discuss several other topics like Definition and focus of Applied Anthropology (how is it different from the traditional four subfields?
ations in groups 6 and 11 What the symbols in the equations represent Transition metals with one charge The number of electrons that fit in each orbital shape Charge trends for specific groups on the periodic table Trends in atomic radii as you move horizontally or vertically on the periodic table How Zeff changes when an atom is ionized What do you need to bring? A non-programmable and non-graphing calculator (ask your TA in discussion section to approve) A pen- so that you can be up for a possible regrade Student ID What will be provided? A periodic table A list of constants and equations All necessary conversion factors What do you need to be able to do/understand? Give the name of a compound based on the chemical formula Give the chemical formula based on the name Give the ground state electron configuration of an atom and shorthand configurations Calculate the energy level of a hydrogen electron based on the wavelength of the photon emittedCalculate the frequency of light emitted when an electron moves energy levels Convert units based on given conversion factors Order particles by atomic radii Calculate Zeff What the difference is between valence electrons and shielding electrons Quantum numbers (what they represent and what are possible values) Applying Coulomb’s Law, Hund’s Rule, Aufbau's Principle, The Pauli Exclusion Principle The why and how of Shielding and Penetration What are some helpful tips? ALWAYS remember to label what the units are Think about the rules of significant figures for your final answers Energy levels will always be a whole positive number You can get partial credit When you start a problem first write the equations you will be using to show where you are heading with the problem (that way the TA will know you understand what to do even if you make minor math errors)
