Nuclear Reactions Intro

Front

What is the force that pushes two positive protons apart inside of a nucleus?

Back

Electromagnetic force.

Front

What is the process of changing one element into another through nuclear decay called?

Back

Transmutation.

Front

In a very large nucleus with many protons, how does the strong force holding the nucleus together compare to smaller nuclei?

Back

The strong force is weaker.

Front

What process occurs when an atom loses particles and energy, leading to transmutation?

Back

Nuclear decay.

Front

What type of charge do protons have?

Back

Positive charge.

Front

What is the role of the strong nuclear force in the nucleus?

Back

It holds protons and neutrons together in the nucleus.

Front

What particles are found in the nucleus of an atom?

Back

Protons and neutrons.

Front

What is the difference between nuclear fission and nuclear fusion?

Back

Nuclear fission is the splitting of a nucleus into smaller parts, while nuclear fusion is the combining of two light nuclei to form a heavier nucleus.

Front

What is radioactive decay?

Back

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

Front

What is the significance of half-life in nuclear reactions?

Back

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