Honors Chemistry - Unit 5 Objectives
Models of the Atom
Learning objectives:
What we did to meet the
objective (include date of
the lesson):
What I learned (include sketches of apparatus,
graphs, particle diagrams, and sample
problems, etc., as appropriate) :
Anything else? (Example,
non-example, important
steps, or pitfalls, etc.)
1. Understand the
progression of atomic
theory by
a. drawing the models
of the atom proposed
by various scientists
b. stating the problem
with each of the
previous models
c. describing the
experimental
evidence that led to
a change in the
previous model
d. recognizing which
features of the new
model were
supported by the
evidence
e. recognizing which
features of the new
model were
“invented” to
complete the model

particles; state each
particle’s

atom
b. charge
c. mass relative to
a proton
3. Distinguish between
the atomic number and
mass number for an
element.
4. Given spectrographs
from a mass

5. Given data of
relative abundance and
mass of isotopes,
determine
a. identity
b. average atomic
mass and/or
c. nuclide notation
of an element.
6. Given data or using
the periodic table
determine the number
of protons, neutrons,
and electrons in a
specific isotope of an
atom or ion.
7. Explain how
different isotopes of an
element are alike;
explain how they differ.
