Which element out of the following three elements is the best insulator?
a) Na
b) Te
c) S
Homework Answers
General convention is that metal is usually insulator however metals are generally conductor,
Hence Na is conductor as it is metallic in nature
Between Te and S, Sulfur is better insulator as non-metallic character decreases down the group of a periodic table
Hence answer is SULFUR, best insulator among S,Te,Na

Problem 1. Assume that Mars formed from chemical elements that were able to freeze out of the cloud of gas around the forming Sun, and that the relative abundances in this frozen-out material was the same as that of solar atmosphere (see belowTable) for Mg, Si, Fe, Na, Al, and Ca. Assume that all elements except perhaps Fe are fully oxidized when they freeze out (as MgO, SiO2, FeO, Na20, Al20s, and CaO). Calculate and tabulate the fractions of the...
