Exit Check 8.4 - Fission and Fusion

Front

What is a Fission Reaction?

Back

A nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What is a Fusion Reaction?

Back

A nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is a Supernova?

Back

A massive star explosion that occurs at the end of a star's life cycle, resulting in the formation of heavier elements.

Front

What is the heaviest chemical element that can be formed in the nuclear fusion of a star?

Back

Iron.

Front

What is the difference between Fission and Fusion?

Back

Fission splits heavy nuclei into smaller ones, while Fusion combines light nuclei to form heavier ones.

Front

What is Radioactive Decay?

Back

The process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is Wave-Particle Duality?

Back

The concept that every particle or quantum entity may be described as either a particle or a wave.

Front

What elements are primarily involved in Fusion reactions in stars?

Back

Hydrogen and Helium.

Front

What is the role of a neutron in a Fission reaction?

Back

Neutrons initiate the fission process by colliding with the nucleus of a fissile atom.

Front

What is the energy source of the sun?

Back

Nuclear Fusion of hydrogen into helium.
