silver, copper, gold, aluminium, lead,

Doesn't matter because I find more lead than all of the others put together.

 Copper before silver otherwise I agree, but silver oxide also conductive thus silver used for electrical contacts.


Real results are
aluminum 26.5  
brass 64  
chromium 126 
copper 17.1 
gold 22.1 
iron 96.1 
lead 208 
lithium 92.8
mercury (0 ℃) 941 
manganese 1440 
nichrome 1500  
nickel 69.3 
palladium 105.4
platinum 105
plutonium 1414  
silver 15.9  
solder 150      
steel, plain 180      
steel, stainless 720      
tantalum 131      
tin (0 ℃) 115      
titanium (0 ℃) 390      
tungsten 52.8      
uranium (0 ℃) 280      
zinc 59

So I am wwwwwwwwwrong

study Q18 

The first three were easy as I knew the answer from way back the last 2 was an educated guess in that I reckon aluminium makes the detector scream a lot more than lead.

Where do I pick up my prize being an all expenses paid trip to WA. lol!

why lead as battery terminals then if aluminium is more conductive?

Aluminium has a high galvanic potential difference between many other metals that come in contact with it and so severe corrosion can set in at contact points. Aluminium develops an aluminium oxide coating on the surface very quickly which helps protect it from further corrosion which might otherwise be caused by weathering conditions. EHV and HV power transmission lines are usually made from aluminium  because of the low electrical losses and the wires ability to cover itself with the protective oxide coating.

No I did not get this from google.
I was a member of the Electricity Commission Main Substation Maintenance Crew in the Southwestern district of Victoria for around six years......A loooooong time ago Very Happy before joining the RAAF.
