Electrons are a crucial part of an atom, playing a key role in chemical reactions. On the other hand, the
nucleus is the core of an atom, where nuclear reactions take place. The strong nuclear force is a
powerful attraction that holds neutrons and protons together within the nucleus.
Discovery of Radioactivity
Henri Becquerel accidentally discovered radioactivity while observing the effect of uranium salts on
photographic plates. Marie and Pierre Curie further explored this phenomenon and identified new
elements, polonium and radium, as well as described the process of radioactivity.
Types of Radiation
Ernest Rutherford identified three types of nuclear radiation: alpha, beta, and gamma radiation. Alpha
particles consist of two protons and two neutrons, carrying a positive charge. Beta particles are high-
speed electrons emitted during the decay of radioactive isotopes. Gamma radiation is a form of high-
energy waves emitted by radioactive nuclei.
Nuclear Decay
Nuclear decay occurs when an atom undergoes a spontaneous change in its nucleus, emitting nuclear
radiation in the process. This phenomenon is characterized by the emission of alpha, beta, or gamma
radiation.
Stability of Atoms
Most atoms are incredibly stable, having existed since the beginning of time. However, some isotopes
are unstable and emit energetic particles, alpha and beta waves, releasing radiation.
