Prior to teaching ionic bonding, I always explain what oxidation numbers are. This resource has students draw Bohr diagrams for the first 18 elements, then electron dot diagrams. (Directions, explanations, and answer keys are provided. These handouts fit in interactive notebooks- see preview). Students will do so in such a way that allows them to see the patterns that exist in the periodic table amongst electron energy levels, valence electrons, and chemical properties. Question handout and answer key provided to help illustrate these ideas. Students (preferrably with teacher) will then read over an explanation of oxidation numbers and how they relate to electron dot diagrams/valence electrons. Students will then label oxidation numbers on a periodic table. One is also provided with oxidation numbers labeled for students who need it.
Please see preview.
This resource is part of my Atomic Bundle
, which includes atomic theory, subatomic particles, organizing the periodic table (one of my best sellers), and ionic and covalent bonding.
Thanks for stopping in! Have a great day!
