Question

Is radioactivity a physical or chemical property

Answer 1

Radioactivity is considered a physical property of matter. It refers to the process by which unstable atomic nuclei lose energy by emitting radiation in the form of particles or electromagnetic waves. This process changes the composition of the nucleus but does not involve the rearrangement of electrons, which is characteristic of chemical reactions. Therefore, radioactivity is associated with the nuclear properties of an atom rather than its chemical properties.
