Name an element which matches the description

1) it is used as a fuel in nuclear reactors

2)it is the only non metals which is good conductor of electricity

3)inert electrodes are made from this metal

1) Uranium

2) Carbon in the form of graphite

3) Palladium

Explanation:

1) In the nuclear reactor the fuel is represented by some uranium isotopes which are easily fissionable.

2) Graphite is made from carbon sheets in which there are free electrons that are moving freely so the carbon, in this form, is able to conduct electricity.

3) Commonly inert electrodes are made from platinum (Pt) or gold (Au) metals, because of the propriety of this metals to not interact chemically very easily with various substances.
