nuclear decay review

Front

What is the result of the nuclear decay of Tantalum-181 (Ta) when it emits a beta particle?

Back

The equation is: ¹⁸¹₇₃Ta --> ⁰_-1e + ¹⁸¹₇₄W.

Front

What are beta particles?

Back

Negatively charged particles emitted from a nucleus at a high speed.

Front

What happens to the atomic number of an element when it undergoes nuclear decay by gamma rays?

Back

The atomic number remains the same.

Front

What force is responsible for holding protons and neutrons together in the atomic nucleus?

Back

The strong nuclear force.

Front

What do we call materials that have unstable nuclei?

Back

Radioactive materials.

Front

What is nuclear decay?

Back

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

Front

What is the charge of a beta particle?

Back

A beta particle has a negative charge.

Front

What is the significance of gamma radiation in nuclear decay?

Back

Gamma radiation is a form of electromagnetic radiation emitted during nuclear decay, and it does not change the atomic number or mass number.

Front

What is the mass number of Tantalum-181?

Back

The mass number is 181.

Front

How does the strong nuclear force compare to electromagnetic force in the nucleus?

Back

The strong nuclear force is much stronger than the electromagnetic force at very short distances, which is essential for holding the nucleus together.
