15. What might contribute to the modern
periodic table changing?
• How is the periodic
table considered a
model?
• What mathematical
information is part of
the periodic table?
• What experiments are
currently being done on
elements?

16. In this lesson, we will learn
• How the periodic
table is organized by
atomic number and
electron levels
• Explain why elements
in the same family/
group of the Periodic
Table have similar
properties
• Use the periodic table
to determine the
atomic number and
atomic mass of
common elements
