Answer 2

The number of protons or atomic number is reduced to 2 by c. Alpha decay.

Radioactive decay:

• The emission of energy in the form of ionizing radiation is referred to as radioactive decay.
• Ionizing radiation can impact the atoms in living things, posing a health concern by causing tissue and DNA in genes to be damaged.
• The released ionizing radiation may contain alpha particles.
• The process through which an unstable atomic nucleus loses energy by radiation is known as radioactive decay.
• A radioactive substance is one that contains unstable nuclei.
• Alpha decay, beta decay, and gamma decay are three of the most prevalent forms of decay, all of which entail the emission of one or more particles.

Alpha decay:

• Alpha decay is a type of radioactive decay in which an atomic nucleus produces an alpha particle (helium nucleus) and therefore transforms or decays into a different atomic nucleus with a reduced mass number and atomic number.
• Alpha decay is a nuclear decay process that occurs when an unstable nucleus emits a particle made up of two protons and two neutrons.
• This expelled particle, known as an alpha particle, is nothing more than a helium nucleus.

Beta decay:

• A radioactive decay in which a beta ray is released from an atomic nucleus is known as beta decay.
• The proton in the nucleus is turned into a neutron during beta decay, and vice versa.
• Beta decay is a type of radioactive decay in physics in which a beta particle is produced from an atomic nucleus, converting the original nuclide to an isobar of that nuclide.

Gamma decay:

• Gamma decay is a kind of radioactivity in which some unstable atomic nuclei spontaneously dissipate excess energy via an electromagnetic mechanism.
• Gamma rays (photons, or packets of electromagnetic energy with extremely short wavelengths) are radiated in the most frequent form of gamma decay, known as gamma emission.
