Which statement describes what is gained or lost during radioactive decay?

Atoms gain other atoms.
Elements take in energy.
Atoms lose smaller particles.
Elements gain smaller particles.

Answers

Answer: The correct statement is: Atoms lose smaller particles during radioactive decay.

Explanation:

Radioactive decay is a process where unstable atomic nuclei lose energy by emitting radiation in the form of particles or electromagnetic waves. As a result of this process, the unstable atoms transform into a different element or isotope. During the decay, the atoms lose smaller particles such as alpha particles, beta particles, or gamma rays. This loss of particles changes the number of protons and neutrons in the nucleus, which leads to the formation of a new element.

statement describes what is gained or lost during radioactive decay: atoms lose smaller particles. That is the third option, as during radioactive decay, the nucleus of an atom can lose subatomic particles, such as alpha or beta particles, which results in the transformation of the original atom into a new atom or a different isotope of the same element.
