Chapter 7 Chemistry
Valance Electrons
Examples
Na = 1
Mg = 2
B = 3
N = 5
F = 7
C = 4
Ne = 8
O = 6
Definition
Electrons in the highest occupied energy level.
Ionic Bonds and Ionic Compounds
Metal/ = Nonmetal
Examples
Aluminum and Chlorine = aluminium chloride = AlCl3
Nitrogen and Sodium = sodium nitride = Na3N
Anions- and Cations+
Anions form when nonmetals gain electrons and Cations form when metals lose electrons.
Examples
Calcium
Loses two electrons.
Oxygen
Gain 2 electrons
Definitions
Malleable
It can be presses into shapes.
Ductile
It can go into wires.
