Question

Which can have either a positive charge or a negative charge when they are released during radioactive decay? alpha particles beta particles positrons photons

Answer 1

The answer is B) beta particles

Answer 2

Answer:

Option (2)

Explanation:

β-decay refers to the process by which the atoms release β-particles.

This type of decay process normally occurs when a particular atom is comprised of higher protons or neutrons in its nucleus. It takes place in two forms, namely-

(a) Positive (+) β-decay -> This type of decay emits β-particles of charge (+). They are known as Positron.

(b) Negative (-) β-decay -> This type of decay produces β-particles of charge (-). They are known as Electron.

These Positron and Electron are elementary particles that are comprised of high energy, in the absence of mass, which are emitted for the conservation of energy during the time of decay.

Thus, the correct answer is option (2).
