Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Radioactive Decay

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This can occur in various forms, including alpha particles, beta particles, and gamma rays. Understanding the type of decay helps predict the particles produced and the resulting changes in the atomic structure.

Rate of Radioactive Decay

Alpha Decay

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of two protons and two neutrons. This process decreases the atomic number by two and the mass number by four, resulting in the formation of a new element. It is common in heavy elements like uranium and radium.

Beta Decay

Beta decay occurs when a neutron in an atomic nucleus transforms into a proton, emitting a beta particle (an electron or positron) in the process. This increases the atomic number by one while keeping the mass number unchanged, leading to the formation of a different element. It is a key process in the stability of isotopes.
