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.
Any excited atomic nucleus can emit a gamma ray. The gamma ray is a quantum of electromagnetic energy, and it really does nothing to the atomic number or the mass number of the atom. A gamma ray can also be emitted when an atomic nucleus decays, and it will appear with another particle or particles in a number of different decay schemes. These decay modes include spontaneous fission, beta decay and alpha decay. As regards a nucleus emitting an electron or positron, these are the two forms of what is called beta decay. A question (with a pretty good answer) can be found by using the link below to the related question, "What is beta decay?"
The charge doesn't change as a result of emitting a photon (which is what a gamma ray is). The mass does change by a small amount (due to the energy-mass equivalence relationship; a photon has no rest mass, but does have energy), but not by enough to make any real difference in the mass number.
Gamma ray (photon) emission represents a reduction in the excitation level of the nucleus, so the emission of gamma rays would cause (actually, its the other way around) a reduction in excitation level of the nucleus.
Gamma radiation changes the Atomic Mass of a nucleus only very slightly. Divide the energy shift by the speed of light squared, 9 x 1018 m s-1, and you get mass shift. This is Einstein's equation, e = mc2, or, in this case, m = e / c2.
Note that the mass shift is inconsequential in comparison with the mass of a proton, for instance. This is because gamma radiation is not directly related to an alpha or beta decay process - it is a side effect - but it is not the direct result.
Mass number does not change with gamma ray emmision
Gamma rays have no charge or mass. It is just light energy traveling through space. Therefore not changing the mass or charge.
When the nucleus of an atom emits a gamma ray, the mass and charge of the nucleus, and therefore of the atom, remain unchanged. This is because a gamma ray has neither charge nor mass.

A proton is a subatomic particle in the nucleus of an atom. Protons have a positive electric charge. The atomic number of an element is equal to the number of protons in the nucleus of one of its atoms. Therefore, if you change the number of protons in an atom, you change the element.
The protons in the nucleus of an atom are called the atomic number or the positive charge of the nucleus.
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
The number of protons in the nucleus is called the atomic number.
Atomic number is the number of protons (i.e. equal to the number of electrons) of an atom.
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
The atomic number is the number of protons in a nucleus.
the number of protons and neutrons
The atomic number is equal to the number of the protons in the atomic nucleus.
what is the atomic number of the nucleus?
The atomic number decreases by one for each beta particle
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.
this depends on the nucleus and will be very positive = +1.6x10^-19 times the number of protons
A proton is a subatomic particle in the nucleus of an atom. Protons have a positive electric charge. The atomic number of an element is equal to the number of protons in the nucleus of one of its atoms. Therefore, if you change the number of protons in an atom, you change the element.
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
The atomic number increases by one unit when a beta decay occurs.
The number of protons in the atomic nucleus is equal to atomic number.
