What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction. However, in nuclear reactions, this law does not always hold true due to the conversion of mass into energy.

Front

Which element is commonly used in nuclear reactions?

Back

Uranium is often used in nuclear reactions due to its ability to undergo fission.

Front

What percentage of our energy comes from coal?

Back

About 50% of our energy comes from coal.

Front

What type of nuclear reaction do most nuclear reactors use?

Back

Most nuclear reactors use fission, which is the splitting of an atomic nucleus.

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

What is nuclear fission?

Back

Nuclear fission is a process in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is the role of neutrons in nuclear reactions?

Back

Neutrons play a crucial role in nuclear reactions as they can initiate fission and help sustain a chain reaction.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is a half-life?

Back

A half-life is the time required for half of the radioactive atoms in a sample to decay.
