that demonstrate an unbalanced electrical charge.
-This happens when the total # of electrons
does not equal the total # of protons.
More electrons than protons = neg charge = ANION
More protons than electrons = pos charge = CATION
Monoatomic ions involve only one atom
Polyatomic ions involve more than one atom
Ex. calcium chloride, CaCl2.
-This causes a slight negative charge near the oxygen and a slight positive charge near the hydrogen.
Ex. Water H2O polarity of water is strong enough to break apart some ionic compounds which causes them to dissolve, or go into solution
solid liquid vapor
