Review ch 4: Atoms and the
Periodic Table
You will be given a periodic table.
Words you should know:
 Atom
 John Dalton
 Niels Bohr
 Proton
 electron
 nucleus
 orbital
 atomic mass
 semiconductor
 nonmetal
element
JJ Thomson
Mendeleev
neutron
Lewis diagram
ion
energy level
group/family
metalloid
Democritus
Earnest Rutherford
Quantum model
Bohr model
valence electron
isotope
atomic number
period
metal
Formulas: not provided on the test, you should know them. Also, you can not
use a graphing calculator on this test. If you want/need a calculator,
bring a non-graphing one.
+
#p = atomic number
#e- = #p+ in a neutral atom
#n0 = atomic mass (rounded off) – atomic number
Things you should be able to do:
 Describe the contribution of different scientists to our understanding of the
atom by describing their model of the atom
 Compare and contrast older models of the atom to the current quantum
theory.
 Read/interpret information from the periodic table (atomic mass, name,
symbol, atomic number)
 Determine the number of protons, neutrons and electrons for any element
 Relate the organization of the Periodic Table to the arrangement of electrons
within an atom
 Explain the relationship between atomic mass and isotopes of an element
 Draw/analyze and interpret Bohr models for elements 1-18
 Draw/analyze Lewis dot diagrams for element in family 1, 2, 13 – 18.
 Tell the number of valence electrons in a group/family
 Relate arrangement of valence electrons to chemical properties
 Identify properties of elements according to their families (metal, nonmetal,
noble gas, metalloid/semiconductor)
 Given the properties of an element, describe to which family (metal,
nonmetal, noble gas, metalloid/semiconductor) it most likely belongs
 Determine the number of valence electrons for any element given its column
on the periodic table (not including groups 3 -12)
 Determine the number of energy levels based on row in the periodic table

Given a description of an element’s properties, identify it’s family/group of
elements
