Do Now Solution 1. Write the Lewis Dot Diagram for K, Mg, P and S 2. Write the Electron Configuration for 2 Nobel Gasses
Metals like to lose electrons and become cations. This will alter their electron configuration.
Nonmetals (other than the Nobel Gasses) like to gain electrons and become anions. This will alter their electron configuration.
- are the result of a complete transfer of electrons from a metal (cation) to a nonmetal (anion). - form compounds that take the shape of a crystal lattice. EX: NaCl Ionic Bonds http://web.jjay.cuny.edu/~acarpi/NSC/5-bonds.htm
Rubidium Chloride Magnesium Sulfide Potassium Iodide Lithium Fluoride Lithium Bromide
When Metals and Nonmetals gain or lose electrons, their electron configuration is altered and they now look like a Nobel Gas.
When Metals and Nonmetals ionize, their Lewis Dot Structure is altered.
Change this to be an activity for composing Lewis Dot Diagrams for Ions Fill in the missing information for the following Ionic Compounds
POGIL - Chemical FOrmulas and Names of Ionic Compounds Portions from the exercise are on the next two slides
Closure: Pass it on Ionic bonds __________________ ____________________________
