Chemistry Unit 4 – Atomic Structure
Consider:
•
•
What is our current understanding of the model of the atom?
How do the locations and numbers of electrons determine how atoms form compounds?
Learning Targets: Students Will:
SCI.CHEM.10.4.1 – Students will present a timeline showing the
scientists and their discoveries in the understanding of our
current atomic theory.
Filling order of
electrons
SCI.CHEM.10.4.2 - Student will describe the location, size, mass
and charge of the sub-atomic particles
SCI.CHEM.10.4.3 - Students will know shapes and abbreviations
of the electron orbitals
SCI.CHEM.10.4.4 Students will construct accurate electron
configurations for elements and ions, using noble gas shorthand
as appropriate.
