Identifying Compounds and Ions
By Jill Larson
Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
