Chapter 6 – The Periodic Table Revisited
Study Guide
• Know how to characterize an as a representative element, transition metal or noble
gas based on its electron configuration
• Know how to write out the electron configuration of an element in s,p,d,f notation
just by looking at a periodic table
• What 3 things influence periodic trends?
• What is the trend in atomic size and you go down a group? Why?
• What is the trend in atomic size as you across a period? Why?
• What is an ion? What causes ions to form?
• What kinds of ions to metals form and why?
• What kinds of ions do nonmetals form and why?
• What is ionization energy?
• What is the trend in ionization energies as you go down a group? Why?
• What is the trend in ionization energies as you go across a period? Why?
• Compare ion electron configurations with noble gas electron configurations.
• What is bigger a cation or an atom of the same element? Why?
• What is bigger an anion or an atom of the same element? Why?

2. • What is the trend in ionic size as you go down a group? Why?
• What is the trend in ionic size as you go across a period? Why?
• What is electronegativity?
• What is the trend in electronegativity as you go down a group? Why?
• What is the trend in electronegativity as you go across a period? Why?
• Know how to use Table S!!!
Summarize periodic trend by drawing arrows on the period table below. Try to do this
from your notes, but check you diagram with page 406 in your notes.
