What is the mass number of gamma rays?
Gamma rays hasn't a mass number.
Which type of radioavtive decay does the mass number remain unchanged?
In gamma decay, the mass number remains unchanged as there is no emission of particles, only high-energy gamma rays are emitted. This process does not affect the nucleus composition, unlike alpha and beta decays which result in a change in the mass number.
When a radioactive nucleus gives off a gamma ray it's atomic number increases by?
Emission of a gamma ray does not change the atomic number of the atom. A gamma ray is a photon, and has no mass. The atom's mass is reduced by the conversion of a tiny amount of mass into the energy of the gamma ray. This changes neither the number of protons nor the number of neutrons. It is done by rearranging the nucleons, changing the state of excitation of the nucleus. An example is when 99mTc emits a gamma ray and changes to 99Tc.
What is the mass of gamma in atomic mass units?
If you mean a gamma photon, it is mass-less.
What happens to the atomic mass and number during gamma ray emission?
The atomic number and atomic mass number do not change as a result of gamma emission. That said, gamma emission is the result of the nucleus stabilizing itself from an excited state that was caused by some event, such as an alpha, beta, neutron, or some other kind of emission. As a result, when you look at the big picture, the atomic number and atomic mass number do change as a function of the event preceding the gamma event. The only time this is a distinct event is in the metastable nuclides, such as Tc-99m, where the gamma emission that follows the beta- emission does not immediately follow it - it can be delayed with a half-life of six hours.
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.
Does The atomic number increases but the atomic mass stays the same in a gamma ray?
yes!!
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.
Do gamma ray have mass?
They are electromagnetic radiation, so no.
What happens to the atomic number when an isotope releases gamma radiation?
It depends on what caused the gamma event in the first place.Strictly speaking, gamma radiation is caused by the de-excitation of the nucleus, so the atomic number (and Atomic Mass) does not change during a gamma event.However, the gamma event is usually precipitated by some other event, such as a beta or alpha decay that does change the configuration of the nucleus. An alpha event reduces the atomic number by 2 (and reduces the atomic mass by 4), while the beta event increases the atomic number by 1 (and does not change the atomic mass very much).Its actually more complex than that, but the answer to the original question is that nothing really happens to the atomic number during a gamma event.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
