GENERAL KNOWLEDGE

Detailed explanation-1: -Radioactive decay is a random process, which means that it is impossible to predict when a particular radioactive nucleus will decay. It is also spontaneous-you cannot cause or influence the decay. However, with large numbers of nuclei it is possibly to statistically predict the behaviour of the entire group.

Detailed explanation-2: -Radioactivity is the random spontaneous disintegration of an atom of an element. The stability of the nucleus depends on the relative numbers of protons and neutrons present. Radioactive disintegration is an example of. (a) a first order reaction.

Detailed explanation-3: -Radioactive decay is the emission of energy in the form of ionizing radiation. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.. The ionizing radiation that is emitted can include alpha particles.

Detailed explanation-4: -Decay is called spontaneous because the occur on their own and are unaffected by external factors like temperature, pressure, and many more. Decay is called random because we cannot determine the rate at which it decays but can only determine the probability of the decay.

Detailed explanation-5: -The rate of decay remains constant throughout the decay process. There are three ways to show the exponential nature of half-life. Equation 11 is a constant, meaning the half-life of radioactive decay is constant.
