Honors Unit 6 Study Guide – Light & Atomic Structure
o Test on Friday, March 23rd
o 60 total points – will be scaled out of 100 points like other unit tests
o Section 1: Multiple Choice – 32 questions (1 pt. each)
o Section 2: Open Ended
 Trends: rank element in order of increasing trend (1 question – 3 pts.)
 Matching: match terms relating to periodic trends (8 terms – 1 pt. each)
 Electron Configuration: write electron configurations, noble gas
configurations, and orbital diagrams for various elements (12 pts. total)
 Light Problem: light calculation using one of the 3 light equations (5 pts.)
Breakdown of Topics:
 Light
o Vocabulary: wavelength, frequency, crest, trough, photon, ground state, excited
state, atomic emission spectrum (a.k.a. bright line spectrum)
o Know the relationship between wavelength and frequency
o Perform calculations involving the 3 light equations (c=λν, E=hν, and E=hc/λ)
o Describe how atomic emission spectra (bright line spectra) are produced (think
of the flame test lab and the gas discharge tube demo!)
o Explain the dual nature of light
 Electronic Structure
o Vocabulary: principal energy level, sublevel, orbital, Aufbau Principle, Pauli
Exclusion Principle, Hund’s Rule
o Understand how energy levels, sublevels, orbitals, and electrons relate to one
another (see the chart at the top of pg. 8 in your notes)
o Know the basic 3-D shapes of the atomic orbitals (s, p, d, and f)
o Understand the three rules for how electrons fill into the electron cloud and be
able to identify mistakes in how they fill (see pg. 12, Part D in your HW packet)
CONTINUE ON NEXT PAGE 
 Electron Configuration
o Write electron configurations using the full format, noble gas configuration, and
orbital configuration (drawing an orbital diagram)
o Identify an element based on its electron configuration
o Identify mistakes in written electron configurations
o Determine the number of valence electrons given either the element or the
electron configuration
o Understand the relationship between the electron configuration/orbital
diagram for an atom vs. an ion
 Periodic Trends
o Vocabulary: electronegativity, atomic radius, cation, anion, ionization energy,
electron affinity
o Know the direction for each of the six trends we discussed in class
o Compare elements and decide which has the larger value for a given trend
o Place various elements in order of increasing trend
o Know the relationship between the size of a cation and the size of the atom
from which it forms
 Same for the size of an anion vs. the size of the atom from which it forms

notes packet, warm-up problems from class, and any homework
assignments we skipped over. Answer keys are posted online as is the
Jeopardy review game. Good luck studying!!
