Nuclear Chemistry Review

Front

What is nuclear fission?

Back

Nuclear fission is the process where a large nucleus splits into two smaller nuclei, releasing energy.

Front

True or False: The risk of harm from radiation increases with prolonged exposure and proximity to the source.

Back

True

Front

What are alpha particles composed of?

Back

Alpha particles are composed of two protons and two neutrons.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two atomic nuclei combine to form a single, more massive nucleus, releasing energy.

Front

What is the charge of an atom's nucleus?

Back

The nucleus is made of protons and neutrons and has a positive charge.

Front

What is the primary difference between fission and fusion?

Back

Fission involves the splitting of a nucleus, while fusion involves the combining of two nuclei.

Front

What type of radiation is emitted during beta decay?

Back

Beta decay emits beta particles, which are high-energy, high-speed electrons or positrons.

Front

What is a neutron?

Back

A neutron is a subatomic particle found in the nucleus of an atom, with no electric charge.

Front

What is the role of the strong nuclear force?

Back

The strong nuclear force holds protons and neutrons together in the nucleus, overcoming the repulsive force between positively charged protons.

Front

What is radioactive decay?

Back

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