What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy atomic nucleus into smaller nuclei, releasing a large amount of energy.

What is nuclear fusion?

Back

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

Where are radioactive elements located on the periodic table?

Back

Radioactive elements are primarily found near the bottom of the periodic table.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when the products of one fission event cause additional fission events, leading to a rapid release of energy.

What are the dangers of uncontrolled nuclear fission?

Back

Uncontrolled nuclear fission can lead to catastrophic events, such as nuclear explosions, as seen in nuclear bombs.

Why is nuclear fusion not widely used for electricity generation?

Back

Nuclear fusion is not widely used because we cannot yet create the extreme conditions of heat and pressure needed for the reaction.

Front

What is the role of control rods in a nuclear reactor?

Back

Control rods are used to absorb neutrons and regulate the fission process, preventing overheating and potential meltdowns.

What is half-life in radioactive decay?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay into a different element.
