−==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.
