Chapter 18 Test Review

Be able to identify elements by their chemical symbol using the periodic table What subatomic particles make up an atom? Indicate the charge associated with each subatomic particle. What are the particles that make up protons and neutrons. Structure of the Atom

Be able to identify atoms (including isotopes) of elements by planetary models. Identify atoms of elements by models representing their electrons. Modeling Atoms

What compromises the mass of the atom? What is the average atomic mass of an atom? What is the mass number of an atom? What units are used to measure atomic mass? How can isotopes be written? What is the difference between isotopes?

(grams  moles) (moles  grams) What causes the nucleus of radioactive elements or isotopes to be unstable? What do these nuclei do to gain stability? Be able to perform the following conversions: (grams  moles) (moles  grams) What is Avogadro's number? What is Avogadro’s Number used for?

Identify elements of the periodic table as: Name the two individuals responsible for constructing the periodic table. Identify elements of the periodic table as: Metals, metalloids, or nonmetals Identify groups/families and periods of the periodic table What is important about each?

Identify the following on the periodic table: Alkali metals Alkaline earth metals Transition metals Boron group Carbon group Nitrogen group Oxygen group Halogen group Nobel (inert) gases Lanthanide series Actinide series Identify the following on the periodic table:

Be able to identify Lewis dot diagrams What are the dots representing? Why are these dots important?
