Question
In the nuclear fission the element which is used for this process is:
- Calcium
- Hydrogen
- Uranium
- Oxygen
Hint:
A silvery-white metallic element of the periodic table with atomic number 92.
The correct answer is: Uranium
- Nuclear fission occurs when a neutron collides with a larger atom, excites it, and splits it into two smaller atoms (also called fission products). Additionally, neutrons may be released, setting off a chain reaction.
- A tremendous amount of energy is released as each atom splits.
- Uranium and plutonium are the most commonly used fission reactions in nuclear power plants because they are easy to initiate and control.
- The energy released by nuclear fission in these reactors heats water to steam. The steam is used to turn turbines, producing carbon-free electricity.
