Essential Question:
Key Questions:
How was atomic structure discovered and how
does atomic structure relate to properties of
the atom?
Can the student explain the history of the discovery of the atom and of
modern atomic theory? Can the student explain diagrams of major
experiments related to the discovery of atomic structure? Which
particle determines the identity of the atom? What are the relative
charges, masses and locations of the proton, neutron and electron?
How is charge number, mass number and atomic number related to
the number of protons, neutrons and electrons within an atom? How
is the formation of ions related to the loss or gain of electrons?
What are isotopes? How is the average atomic mass of an element
calculated and what information is needed for this calculation?
What determines whether or not a nucleus is stable or unstable?
What is radioactive decay and what are the three types of decay?
How are equations showing alpha and beta decay written? How does
fusion differ from fission? What is half-life and how is it used

Higher-Order Student Engagement
SC1 Students will analyze the nature of matter and its classifications.
a. Relate the role of nuclear fusion in producing essentially all elements heavier than
helium
b. Identify substances based on chemical and physical properties.
SC3 Students will use the modern atomic theory to explain the characteristics of atoms.
a. Discriminate between the relative size, charge and position of protons, neutrons
and electrons in atoms
c.
Explain the relationship of the atomic number to the elements identity
d. Explain the relationship of isotopes to the relative abundance of atoms of a
particular atom.
