This worksheet was designed as an in-class, group activity in a flipped classroom. It relies on an understanding of the octet rule and common charges of various elements, as well as basic nomenclature of ionic compounds.  The worksheet teaches students to balance simple redox reactions (in which only the oxidized and reduced atoms are present) by identifying half-reactions, counting electrons transferred, and multiplying half-reactions to "cancel" electrons.  

This is a worksheet designed for a flipped-classroom, in-class activity during the first course in our chemistry sequence.  It teaches the basics of Molecular Orbital Theory from a semi-qualitative standpoint, by showing the constructive and destructive overlap of s-orbital "wavefunctions."  The activity  illustrates the formation of the bonding and antibonding molecular orbitals in H₂, shows its molecular orbital diagram, and introduces the concept of bond order.
