I'm trying to label a galvanic cell that has lead and zinc electrodes. I'm not sure how to decide which is the anode and which is the cathode, which direction electron flow is happening in the wire, which direction ion flow is happening in the anode and cathode solution, and which direction ion flow is happening in in the salt bridge. 

I know that by convention, the Anode should be on the left and the Cathode should be on the right, but I don't know which element should be assigned to which electrode.

Alright then!

anonymous · Answer

You know that the flow of electrons should be from negative (anode) to positive ( cathode). Now all you have to know is the difference in oxidizing potential of your elements. In other words, ehich one loses more electrons or in even simpler words, which one is more reactive.

anonymous · Answer

According to your example, the most electropositive should be at the anode, because remember, the more the electropositivity, the more likely is to oxidize (lose electron). 
Pb is -0.13 and Zn is -0.76, therefore Pb is at the anode and Zn at the cathode.

Yeah, I figured it out. Thank you, nonetheless!
