    Hi,

    I was wondering if it is possible to relate the position of an element on the periodic table to the electrical resistance in a wire composed of that element.

    I have found lots of information on factors affecting resistance, but it's all very basic stuff about length, cross sectional area etc. I would like to know what microscopic properties of wires affect its resistance (e.g. number of valence electrons, atomic mass) and how these properties affect the resistance. Would it be viable to conduct an experiment using wires of different materials to see the impact of these different properties?

    Thanks

    Ag,Cu,Au ,Al ,Be,Ca,Mg,Rh, Na are the first 9 in increasing order. the rest follow according to this table --- http://environmentalchemistry.com/yo...lectrical.html
    yes you could fabricate equal size wires and measure but its aready been done.
    Have Fun
