On Friday we talked about ionic bonding. An ionic bond is when a metal gives up electrons to a non-metal. The atoms now have a positive charge (the metal) or a negative charge (the non-metal). Just like magnets, opposites attract and a salt is formed.
For some classes, we tackled ionic compounds with more than two ions. Remember, positive and negative charges have to balance out. See the PowerPoint for more information on writing ionic formulas.
Aim: What happens when an atom gains or loses electrons from more than one atom?
