Answer 2

Answer:

Heya!!!

Here you go ⏩⏩⏬⏬

Explanation:

1. Radioactivity is the spontaneous emission of radiation as particles or high energy photons which results from a nuclear reaction.
2. It is also the property possessed by some elements (like uranium) or isotopes (such as carbon 14) of spontaneously emitting energetic particles (such as electrons or alpha particles) by the disintegration of their atomic nuclei also : the rays emitted

There are three types of radioactivities

• Alpha-the fast moving helium atoms.
• Beta- fast moving electrons.
• Gamma-thesr are the photons just like light except much higher energy.
