CHEM 1110 STUDY GUIDE and ADVICE for Exam 1 Friedman
Covering chapters 1, 2 and 3
Exam questions typically consist of an assortment of simple definitions, concepts, and
problem solving. You should use the content discussed during lecture and in the video
content as a guide of what to focus on - most of that is emphasized in the homework
assignments and quizzes. Below is a list of subjects that we covered in Chapters 1, 2 and 3.
This list is not necessarily comprehensive, but should help you stay focused in your studies:
matter chemical change ions and isotopes
density intensive property chemical reaction
protons, neutrons, electrons extensive property pure vs. mixture
physical property element homogeneous mixture
physical change compound heterogeneous mixture
chemical property neutral atom/molecule
The scientific method Exact and inexact numbers
States of matter (solid liquid gas) Atomic mass, molecular mass, and molar mass
Data accuracy and precision The mole
Electromagnetic spectrum Orbital Energy Levels and degenerate orbitals
Absorption and emission spectra Orbital Diagrams
Quantum Theory and the Planck constant Electron Configurations
The Bohr Model of atomic structure Isoelectronic
de Broglie Wavelengths Valence shell and valence electrons
Heisenberg uncertainty principle Effective Nuclear Charge (Zeff)
Orbitals Ionization energy
Pauli exclusion principle Electron affinity
aufbau principle Atomic radius
Hund’s rule
Know the various units and what symbols represent them, and be able to convert from one
unit to another using the specific conversion factors provided.
Know the rules for determining significant figures and proper rounding of numbers.
Understand scientific notation, how to convert between scientific notation and floating decimal.
Understand the difference between atomic number, mass number, and atomic mass/weight.
Know how to determine the number of protons, neutrons and electrons in an atom based on
the information provided in a nuclide symbol or from the periodic table.
Understand what a weighted-average is, and how that applies to calculating the atomic
masses that are listed in the periodic table.
Understand the experiments discussed in class and how the results informed new theories of
atomic structure: JJ Thomson’s experiment with cathode rays, Milikan’s experiment
with the oil drops, Rutherford’s experiment with gold foil and alpha-particles.
Understand what Mendeleev did and the significance it brought to building up the modern
periodic table of the elements.
Know the various groups (families) of elements such as the alkali metals, alkaline earth
metals, chalcogens, halogens and noble gases.
Know the basic characteristics of metals, non-metals and metalloids.
