2 + _ battery compass Coil of wire + _ The compass will align with the coil of wire if current is flowing. Even though a battery is connected, no electrical current is flowing through the water.

3 + _ battery compass Coil of wire Copper Chloride + _ Copper chloride is added to the water. It dissolves in the water.

4 + _ battery compass Coil of wire Copper Chloride If copper atoms are going to the negative side, what charge do they have? What about the chlorine atoms? + _

5 + _ battery compass Coil of wire Copper Chloride Since the atoms wandered towards each side, lets call them IONS from the Greek word, ion, meaning wanderer. + _

6 + _ Copper Chloride CuCl Also, since the positive side of a battery is called the anode (way up), well call ions that go towards it anions Since the negative side of a battery is called the cathode (way down), well call ions that go towards it cations. The ions that go towards the positive anode are called anions. anode cathode + _

15 For ionic compounds with a metal from group 1A, 2A, & 3A place the metal first and name it first. The non-metal is put last and named last. The number of metals or non-metals is depends on how many it takes to balance the charges IA IIA IIIAVIAVAIVA VIIA VIIIA
