Gamma decay is primarily "energy only", in that it is the emanation of photons that represent energy. However, and this is important to understand, gamma does not exist by itself - gamma is a secondary reaction to a primary reaction that involves a change to the nucleus - a change that is usually represented by alpha or beta decay.
So, with the exception of the few metastable forms of radionuclides, gamma still, ultimately, is preceded by particle emission. (Even in the metastable forms, the gamma is preceded by particle emission - its just that the event is delayed enough to "count it" as a separate event.)

Which characteristic best describes how nuclear decay differs from nuclear fission?
Energy
What are the two quantities are always conserved in nuclear decay equation?
Energy and electrical charge are two quantities that are always conserved in nuclear decay equation.
Is nuclear decay an example of a nuclear change?
Yes, it is. Nuclear decay is a process that an unstable atom goes through to lose energy and move toward a more stable state. (It may take more than one decay.) In nuclear decay, the nucleus undergoes a change by releasing a particle or particles and electromagnetic energy. Links are provided to related Wikipedia articles and related questions.
What actually decays in radioactive decay?
The nucleus of the atom decays, and in the process, the nucleus transforms into another element, or into an isotope or isomer of the same element. In radioactive decay, the nucleus always emits some kind of particle(s). It is the high-energy emission of these particles that we call radiation. There are many different types of radioactive decay:Alpha decay results in the emission of an alpha particle (two neutrons and two protons)Beta decay results in the emission of a beta particle (an electron or a positron)Neutron decay results in the emission of a neutronProton decay results in the emission of a protonGamma decay results in the emission of a gamma particle (a photon)Neutrino decay results in the emission of a neutrino or antineutrinoIn some cases, a combination of the above emissions takes place. For example in double beta decay, a single nucleus emits two electrons and two antineutrinos in the same event.
Which equation represents a spontaneous nuclear decay?
All nuclear decay is spontaneous.
What term is defined as the emission of energy from subatomic particles?
Radioactivity is the term defined as the emission of energy from subatomic particles.
What are the four types of nuclear decay in order?
The four types of nuclear decay are alpha decay, beta decay, gamma decay, and neutron decay. Alpha decay involves the emission of an alpha particle, beta decay involves the emission of beta particles (either electrons or positrons), gamma decay involves the emission of gamma rays, and neutron decay involves the emission of a neutron.
What are the characteristics of the alpha decay band in nuclear physics?
In nuclear physics, the alpha decay band is characterized by the emission of alpha particles from a radioactive nucleus. This process typically involves the release of a helium nucleus, which consists of two protons and two neutrons. The alpha decay band is associated with certain specific energy levels and decay patterns within the nucleus.
What nuclear decay have no mass and no charge?
Gamma decay involves the emission of a gamma ray, which is a high-energy photon with no charge and no mass.
A emission results in the release of energy without any apparent change in mass or nuclear charge.?
This process is known as gamma decay, which involves the emission of a gamma ray photon. Gamma rays are a form of electromagnetic radiation that carries energy but does not change the mass or nuclear charge of the atom. Gamma decay is typically associated with nuclear reactions and can occur after alpha or beta decay to stabilize the nucleus.
Which form of radioactive decay consists of photons?
Gamma decay consists of the emission of gamma rays, which are high-energy photons. This type of radioactive decay occurs when an unstable nucleus releases excess energy in the form of gamma rays to become more stable.
Why is radium warm?
Radium is a warm as a consequence of energy release by nuclear reactions - radioactive decay with the emission of alpha, beta and gamma rays.
The process by which high-energy particles and rays aare released?
This process is called particle radiation or particle emission, and it occurs when high-energy particles such as alpha particles, beta particles, or gamma rays are released from the nucleus of an atom. This emission can happen during radioactive decay or in nuclear reactions.

Is nuclear medicine a fusion or fision?
Nuclear medicine involves the use of radioactive materials, which typically undergo nuclear decay processes such as beta decay or gamma emission to emit radiation for diagnostic or therapeutic purposes. This is a form of nuclear fission rather than fusion, as it involves the splitting of atomic nuclei to release energy.
How and why does atomic nuclear decay occur?
Atomic nuclear decay occurs when an unstable atomic nucleus releases energy in the form of radiation to become more stable. This process can happen due to the imbalance of protons and neutrons in the nucleus, leading to the emission of alpha, beta, or gamma particles. The decay helps the nucleus achieve a more balanced state and reduces its energy level.
Order gamma decay beta decay and alpha deacy form weakest to strongest?
From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
