What happened

Does an elements conductivity depend on its position on the periodic table?DiscussionAfter the experiment, you may think that the results clearly show that my theory was wrong. It is, on a broad scale, but after throughly studying the results, I found that I wasn't entirely wrong. All of the Transition Metals that I experimented on inclined in the pattern that I predicted. I am only taking a estimate here though; I would have to test all of the Transition Metals to prove it, but I can't as of now.The amount of electricity an element can conduct is not defined by the Periodic Table. It depends on the type of substance it is. For instance, if i compared the conductivity of Arsenic to Gold, Arsenic would be more conductivve because it is a liquid, even though Gold os higher up the Table.Some elements (as shown in the Result Table) can't conduct electricity. For instance, the Sulphur Powder; it can't conduct in powder form, but it may in a more solid form. Or liquid metal might conduct more that its solid counterpart. Therefore, the amount an element can conduct also depends on the state in which it is in.

1. Collect all of the materials.2. Attach one cord to the Battery and the Amp, one cord to just the battery and one cord just to the amp.3. Attach an element to the two spare ends.4. Allow the Amp Needle to settle.5. Record reading.6. Repeat steps 3-5 for each element.

Hypothesis

I believe that the more mass an element has the more conductive it will be. Therefore, the pattern that should arise is an incline in the amount of amps each element can take.ConlusionI conclude that the conductivity of elements is not set in the writing of the Periodic Table, it all depends on the type of substance they are. Meaning a liquid is more conductive than a metal, different types of gases are at differnet levels of conductivity etc.Acknowledgments: I would like to thank Michelle for taking her time to organise all of my materials and writing up loads of hazardous materials pages. I could not have conducted my experiment without her help.Just made a pun in the last sentence there.

    Nice pun Noah and fantastic report/experiment! You worked extremely well in class and should be proud of the way you conducted yourself....
