==Concept #==
==Concept #1 Early Atomic Models==
===Learning objectives===
===Learning objectives===
#Understanding of the atom evolved as experiments demonstrated results
#Current accepted model of atom rests on principles of quantum theory
#It is important to remember that atoms are not circles; though we use circles to represent

''These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.''

==Concept #==
==Concept #2 - Electrons occupy different energy levels in an atom
===Learning objectives===
===Learning objectives===
#Electrons are distributed in an atim
#They occupy different levels based on energy
#There are parameters that define what levels an electron can occupy
===Notes for teachers===
===Notes for teachers===
It is important that students do not think of the electrons as "orbiting" the nucleus like the planets around the Sun.
