Questions:

1. How nuclear energy is used to solve energy scarcity? Earth has a limited amount of oil and coal, and when these amount ends, nuclear power plants can still produce energy, so that helps to still produce energy when earth resourses ends.

2. How is nuclear energy produced? When changes occur in the structure of the nuclei of atoms, the name of this change is nuclear reaction. Energy that is created in nuclear reaction is called nuclear energy or atomic energy.

a) What is nuclear fission? Is a process of splitting the nuclei of atoms which releases energy.

The picture above shows a nuclear chain reaction. It shows the neutron bombarding into the target nucleus. And by doing that, the atoms multiply, and creates a chain reaction.

b) How is nuclear energy used to generate electricity? Uranium chain reactor is placed tanks os water inside the nuclear reactor.

3. What are the advantages and limitations of nuclear energy? Advantages:
 * Earth has a limited amount of oil and coal, and when these amount ends, nuclear power plants can still produce energy.
 * Burning oil and coal releases pollution in the air, and well-operated nuclear power plants don't release pollution in the air.
 * Genrate a lot of electricity.

Disadvantages:
 * When nuclear explodes, it produces a lot of radiation in to the air, and it is really bad for the environment and our health.
 * Nuclear reactors only last for about forty to fifty years.

4. How does nuclear radiation affect the environment?

Nuclear energy creates a waste that is extremely toxic and that must be kept in remote areas. The actual fuel after is used has to be kept away for year and years away from people, because of how toxic it is, it can kill people. But comparing with the coal waste is nothing (quantanti).

5. How does nuclear radiation affect health?

When cells and all the complements of it get exposed to radiation, components of DNA and proteins within the cell get ionized, meaning that the electrons with our atoms get kicked out, causing the DNA strands to break and the proteins to cramp up.
