I can define valence
electrons and can explain how they are involved in forming
compounds.
Valence electrons are electrons on the outermost shell of an element. They are involved in chemical reactions. They can be gained, lost, or shared.

Valence ElectronsCopy this on your folded periodic table.
Valence electrons are electrons on the outermost electron shell of an atom.
Valence electrons are responsible for chemical reactions!
The number of valence electrons determines whether an atom of an element will lose, gain, or share electrons in a chemical reaction.
