∙ 13y agoIn Beta- decay, a nucleus has a neutron change into a proton by the emission of a W- boson, which then changes into an electron and an electron antineutrino.
In Beta+ decay, a nucleus has a proton change into a neutron by the addition of energy, and it then emits a positron and an electron neutrino.

∙ 10y agoThe gamma ray itself (the photon), which is the energy released during the reaction. The reaction itself occurs before this, and may release alpha or beta radiation, depending on the specific reaction. The following section from the Wikipedia explains it very well: Gamma rays from radioactive gamma decay are produced alongside other forms of radiation such as alpha or beta, and are produced after the other types of decay occur. The mechanism is that when a nucleus emits an α or β particle, the daughter nucleus is usually left in an excited state. It can then move to a lower energy state by emitting a gamma ray, in much the same way that an atomic electron can jump to a lower energy state by emitting a photon.

Which type of decay does not result in the change of one element into another?
the loss of gamma radiations alone from an unstable heavy metal nucleus results in no change in masss number nor the atomic number
Does the nucleus mass or atomic number change during gamma ray decay?
The emission of a gamma ray changes neither the mass number nor the atomic number of a nucleus. An example of an equation for gamma emission is: 99mTc --> 99Tc + gamma The "m" associated with the mass number indicates a metastable nuclear isomer.
What is the decay that releases only energy no particles called?
That is gamma decay, which is caused by a change in energy levels within a nucleus, but which does not result in any change to the number of protons or neutrons. A nucleus of one particular isotope can have different energy levels, these are called isomers of that isotope. The gamma radiation is electromagnetic, similar to x-rays but a higher frequency and hence higher energy.
The least energetic of the forms of radioactive decay is ______?
alpha decay
Which form of radioactive decay consists of photons?
Gamma rays.
High-energy light waves that are released from a radioactive nucleus during alpha decay and beta decay?
Gamma rays, which are photons with a certain energy step change, are emitted from the nucleus when the nucleus is returned from an excited state back down to ground state, as often occurs during alpha and beta decay.
How is the atomic number of a nucleus change by gamma decay?
In gamma decay ,nucleus lose a charge of -1 and the daughter nucleus has charge of Z+1.
He high energy photon emitted by a nucleus during fission and radioactive decay?
gamma ray
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
Magnesium
The emission of electromagnetic energy from an atomic nucleus is called decay?
gamma
Which type of radioactive decay does not change the neutron-to-proton ratio for a nucleus?
only the gamma decay.
What do a gamma ray gives off?
Gamma decay occurs when an atomic nucleus changes from a higher energy state to a lower one. When it does the "extra" energy leaves in the form of a gamma ray. That's gamma decay. The gamma ray is electromagnetic energy. That means that there is not a particle of anything involved in this event. Gamma decay is the emergence of that gamma ray from the nucleus of an atom that is going down in its energy state
What type of radioactive decay releases energy from the nucleus without a change of protons neutrons?
This is a gamma-decay.
Why do some researchers complain when the emission of a gamma particle is called gamma decay?
Because its not a decay process. Gamma is an emission of energy in the form of photons from the nucleus when the nucleus changes from one energy level to a lower energy level. It is true that this is often preceded by a decay event, such as alpha or beta, but it is a distinct, non decay, event.
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
What type of radioactive decay involves only the release of high energy photons and therefore does not change the mass of the radionuclide?
There is no normal process by which a nucleus can release energy without changing the element. Even gamma radiation, which is photon emission from the nucleus during a restabilization sequence, has a predecessor, i.e. usually beta or alpha, which does change the element.
What products are released during decay?
There are 4 different types of decay, the first is alpha decay this releases a helium nucleus ( 2 protons and 2 neutrons) the second is a beta particle also known as an electron. The third is beta minus decay which is a positron, it is the same as an electron in every way except it has a positive charge where as an electron has a negative charge. The last is gamma decay, which releases a gamma ray, this is a type of electromagnetic wave.
