All of their scientific discoveries and contributions lead to….

All of their scientific discoveries and contributions lead to….

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?

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
