Derricks page on chapter 13 __definitions__ Valence electrons-The electrons in the outer energy shell. Chemical bonding- The force of attraction that holds atoms together. Hyroscopic-absorbs water easily

__Covalent bonds__

can be shown with electron (or lewis) dot diagram. compounds made by sharing valence electrons compounds are called molecules only in covalent bonds simplest forms are called diatomic molecules

__Metallic bonds__

electrons are shared throughout the compound. properties of these compounds include conductivity, malleability, and ductility only happen between metals __Ionic bonds__

formed between a metal and nonmetal compounds made by atoms losing or gaining electrons, making ions that attract eachother The negative ion changes its name to end in "ide"

FIREWORK INFO

[] [] There is one problem with the Chloride compounds. They are hygroscopic materials. This means that they absorb water easily, deminishing the color effect.
