Valence Electrons The number of electrons in the outer shell of an atom
Hydrogen has one valence electron; its in the Alkali Metal Family Copyright © 2010 Ryan P. Murphy
Hydrogen has one valence electron; its in the Alkali Metal Family Copyright © 2010 Ryan P. Murphy
Hydrogen has one valence electron; its in the Alkali Metal Family Copyright © 2010 Ryan P. Murphy
All other elements in this family, Li, Na, K, Rb, and Cs, also have only one valence electron. Copyright © 2010 Ryan P. Murphy
Fluorine has seven valence electrons Copyright © 2010 Ryan P. Murphy
This places it in the halogen family Copyright © 2010 Ryan P. Murphy
