Exploring Trends Across the Periodic Table
The periodic table is designed to reflect the key properties of all of the elements. This module gives an overview of the trends we see within each group of the periodic table. This module addresses NGSS Performance Expectation HS-PS1-1 by having students analyze trends in the periodic table in relation to atomic radius and first ionization energy.
Students learn: The relative sizes of elements in the periodic table; The definitions of atomic radius and first ionization energy; and How trends in atomic structure relate to trends in first ionization energy and atomic radius.
