When an isototope undergoes alpha decay which of the following change?

Gamma radiation results from the nucleus being placed in an excited state due to some prior event, such as alpha or beta decay.
The nucleus "wants" to release its excess energy, so it does so. When it does, a photon is emitted. This is the gamma radiation. There is a comparable sequence involving the electron cloud. In that case, the resulting photon has less energy, and is characterized as an x-ray, rather than gamma.
Under normal conditions, the gamma event occurs immediately (about 1 x 10-12 seconds) after the initiating event. However, some nuclides have a meta-stable form, where the gamma event is delayed substantially after the initiating event - say for a few hours or even a day or so.
There are many examples of meta-stable isotopes. One that comes to mind is Tc-99m, which is used as a tracer in various medical scanning technologies such as a heart scan or bone scan. The advantage of this is that the body is not subjected to the stronger impact of the initiating event - just the gamma event - and that can be seen with gamma scanning instrumentation.

∙ 12y agoThere is insufficient information in the question to properly answer it. You did not provide the list of "the following".
In general, however, during alpha decay, the atomic number decreases by 2 and the Atomic Mass number decreases by 4. For instance, 92238U decays by alpha decay to become 90234Th.

What product is produced when 232 90 Th undergoes alpha decay?
90Th232 undergoes alpha decay to form 88Ra228. Remember, in alpha decay, a helium nuclei is emitted, comprising two protons and two neutrons. As a result, the atomic number goes down by 2, and the atomic mass number goes down by 4.
Beta decay of neodymium-144?
Nope, Neodymium-144 undergoes Alpha decay to Cerium-140.
Alpha decay and beta decay are two forms of decay that cause transmutation?
Transmutation, which is the change of atoms from one element to another.
Is uranium 238 a slow or fast neutron absorber?
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
What is a nucleus that is unstable and undergoes decay?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
The answer is D. All of these change.
How can the element Americium change into the element neptunium?
Americium decays into neptunium-239 through alpha decay. It has a half-life of 7,370 years.

When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
