Question

A scientist notices that a lump of niobium is warm to the touch and wonders if nuclear reactions are taking place in the metal. How can she find out?.

Answer 1

A scientist can find out whether a nuclear reaction is taking place or not by inspecting the presence of alpha, beta, and gamma particles.

What is Nuclear Reaction?

A nuclear reaction may be defined as a strategy in which the nucleus of an atom is transformed by being shattered apart or united with the nucleus of another atom.

The complete question is as follows:

• Measure the metal’s temperature.
• Check for the presence of alpha, beta, and gamma particles.
• Look for the presence of niobium compounds.
• Place the niobium in a pressurized container, and see if the lump becomes warmer.

Therefore, the correct option for this question is B. This is because the influential existence of these particles is a characteristic indicator of radioactive decay which means unstable atoms spontaneously experience a nuclear reaction.

Answer 2

Checking for the presence of alpha, beta, and gamma particles will determine if nuclear reactions are taking place.

What is a Nuclear reaction?

This reaction occurs when two or more nuclei fuse together to form a new one and is characterized by heat also.

Its unique property is the presence of radiations which is why the presence of alpha, beta, and gamma particles should be checked.
