Honors Chemistry: Unit 04 Molecular Structure Student Learning Maps
Key Learning(s):
Molecules are made up of atoms.
A molecule is the smallest particle of a compound that still retains that compound’s properties.
The structure and composition of a molecule determines its properties.
Unit EQs:
How does the concept of matter seeking its most stable configuration explain the chemical and physical properties of elements?
Why is the periodic table a chemist’s best friend?
Students will know:
