A chemist is trying to identify a sample of metal that is listed in this table. She passes an electrical current through the sample and finds that, of the metals listed in the table, it’s one of the best conductors. Then she heats the metal to 1000°C, which is the highest temperature her heater allows. The metal doesn’t melt. Which type of metal does the chemist have? Material Melting Point (°C) Electrical Conductivity Ranking
aluminum 660 3
copper 1085 2
zinc 420 4
silver 962 1
nickel 1455 5

Nickel :)

Nickel has the highest meltdown point

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
