Lewis Dot Structure Worksheet
In this molecules worksheet, students determine the Lewis dot structures for 25 given molecules and determine the physical properties of molecules based upon polarity and intermolecular interactions.
Curated OER
Atomic Structure
Students explore atomic structure. They observe a video on atomic structure and complete a Venn diagram on the parts of the atom. Students create their own graphic organizer on the parts of the atom using Inspiration software.
