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.

Answer:
John Dalton:
John Dalton was the scientist who introduced atomic theory in the field of chemistry. Dalton worked on different gases and formulated this theory. The main points of Dalton's theory are:
- Every element present is made up of atoms.
- Atoms of an elements are have the same same properties whereas these properties are different for each element.
- According to his theory, an atom could not be broken down.
- Different atoms combine or get separated from each other during a chemical reaction.
Ernest Rutherford:
Ernest Rutherford is known as the father of nuclear physics due to his impressing research work on radioactivity of atoms. Rutherford was the first scientist to discover the nucleus of an atom and prove that the nucleus was charged. He also described that the electrons circle around the nucleus of an atom.
The correct answer is Phospholipid
