Concepts and Skills for Trimester 2
Cumulative Test - 2014
Important Notes:
1. Your Trimester 2 Cumulative Test on Friday, March 21st will be made up as follows:
 50% will be questions/problems on single replacement, double
replacement, net ionic equations, redox and stoichiometry (Chapters 8
and 9)
 50% will be review questions from Chapters 5, 6, 7, 8, organic
nomenclature)
2. The questions on the review portion of the test will come from the concepts/problem
skills listed below.
3. The contents of this list do not indicate that other concepts are not important.
Chemistry is a cumulative subject and everything we learn is important. I have simply
narrowed down the possible review concepts for you.
Chapter 5 – Periodic Properties
 Knowing period and group trends for atomic radius, ionization energy,
electronegativity and why
 Knowing why there is a huge jump in one of the ionization energies for certain
metals.
 Knowing location of metals, metalloids, nonmetals, transition metals, and noble
gases on periodic table.
 Knowing how the radius of a cation and anion compares to its neutral atom and
why
Chapter 6- Chemical Bonding
□ Given the formula of a molecule:
 Draw its Lewis Structure
