Periodic Table

Develop and apply models of atomic structure to explain the arrangement of elements within the periodic table.

Understand how the periodic table serves as evidence for the nuclear model of the atom, with electrons organized in distinct energy levels.

Explain how the periodic table systematically organizes known chemical elements to account for their varied physical and chemical properties.

Focus specifically on the unique properties, trends, and reactions of the elements found in Groups 1, 7, and 0.
