∙ 12y agoGamma decay occurs when the nucleus undergoes an energy state change without actually changing the number or ratio of nucleons. The element remains the same element.
Technetium-99m (99mTc) is an example of such an atom. Its nucleus is the isomer of Technetium-99 (99Tc), and as an isomer, Technetium-99m rests at a higher energy state than the ground state Technetium-99. Both variations of Technetium-99 have exactly the same number of protons and neutrons. The technetium-99m nucleus spontaneously decays to the stable technetium-99 through emission of a photon, or gamma particle, with a half life of 6 hours.

What are the steps of radioactive decay through which a beta particle is released?
Beta decay is a type of radioactive decay that comes in two types. The beta plus decay and beta minus decay can be described by use of an equation that places an unstable atom on one side and the products of the beta decay on the other. The beta minus decay of carbon-14 is just a single example of this equation, and here it is: 614C => 714N + e- + ve To learn more about beta decay, use the link below to the related question, "What is beta decay?"
Does a free neutron decay into a hydrogen atom?
A free neutron actually decays into a proton, and an electron and an antineutrino are ejected in the process. This is beta minus decay, and a free neutron is unstable and will decay by this mechanism. While it is true that a proton and an electron make up a hydrogen-1 atom, the decay of the neutron is slightly different. The reason is that the electron leaves the decay event with a high kinetic energy, and it cannot be "held" by the proton (to create the hydrogen atom). Certainly the proton will "pick up" an electron from somewhere after is slows down a bit following its creation, as it, too, has some kinetic energy. The proton will have to release that kinetic energy through scattering, just like the electron that left the event. Links can be found below to related questions with descriptive answers.
Discuss with the use of examples the main differences between alpha and beta decay?
In alpha decay, an alpha particle (a helium nucleus - 2p+ and 2n0) is emitted from the nucleus of an atom. In beta decay, a neutron turns into a proton and an electron, and the electron (beta particle) is emitted from the nucleus of the atom.
What is released from the nucleus during gamma decay?

What are the changes to the atom during gamma radiation?
Gamma emission is not a decay process. It is a restabilization process of the nucleus in response to some other decay process, such as alpha or beta, which leaves the nucleus in an excited state. When the nucleus comes down from that excited state it emits a photon of energy equal to the step change in energy that was made. Short answer: The atomic mass or atomic number of a nucleus is not changed, specifically, by the gamma emission, but it is changed by the precipitating alpha or beta (or other) event that left the nucleus in an excited state. Slightly more correct answer: The mass of the nucleus is decreased by the equivalent mass of the loss of energy that occurs. This ratio is e=mc2, where c2 is 9 x 1018, so you can see that the delta mass due to gamma emission is very, very small.
Does a radioactive isotope decay at a varying rate from the time it forms?
The probability of decay of any particular atom is a constant. However, as time passes, the there are fewer atoms left to decay. So in that respect the number of decay event falls.
What happens to radioactice substances when they decay?
The atom that decays leaves emits some radiation, and leaves behind another type of atom (or atoms), with less mass (the mass of the original atom, minus the mass that left the atom). There are several common types of radioactive decay. In alpha decay, an alpha particle is emitted. This is two protons and two neutrons bound together. In beta decay an electron or positron is emitted. Excited nuclei may shed their excess energy by emitting a neutral gamma ray. Some nuclei even emit neutrons (the fission products in a nuclear reactor are especially prone to this). And sometimes the nucleus may grab an orbiting electron in "K-capture". Some of these events alter the nucleus's charge thus changing it into a different chemical element. In addition, the proton-to-neutron balance may be changed enough to make the new nucleus unstable so it decays again. In most cases the decay leaves the nucleus in an excited state which may destabilise it resulting in further decay too. It is not uncommon for a material to decay through several generations at hugely different rates. But eventually the nucleus settles down as a different chemical element, the orbiting electrons re-shuffle and, well, that's it. The substance therefore changes into another one. Since the processes are very specific for every isotope, the composition of an old rock, for example, can give us complete information about what was in it a thousand, a million, a billion years ago.
An atom 134 84Po of decays by alpha decay Which atom is left after the decay?
Since an alpha particle contains 2 neutrons and 2 protons (for a total of 4 nucleons), you are supposed to subtract that from the nucleus. In other words, you will get isotope 171 76 (4 nucleons less, 2 protons less). APEX 171 76 Os
Will the decay product ever rach to 100?
I assume you mean, that 100% of a product decays. In radioactive decay, in purely mathematical terms, this will never happen; but for practical purposes, after several half-lives elapse, the amount of remaining substance (of the original substance) is so small as to be insignificant for most practical purposes. Also, since a material is made up of individual atoms, the time will come when (once again, in a purely mathematical way) much less than one atom is left; what this means in practice is that the probability of even one atom being left becomes insignificant.
When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
When radioactive decays stop?
It will stop when there is nothing left to decay. There is basically no way to stop certain nuclides (isotopes) from decaying.
What fraction of a radioactive sample decays after three half lives?
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.

What does it mean by the statement The decay of unstable radioactive nuclei is totally random?
It means that you can't predict when an individual atom will decay. If a certain isotope has a half-life of 5000 years, that means that if you have a large number of atoms, half of them will decay after 5000 years. After another 5000 years, half of what is left will decay - only 1/4 of the original amount is left. For an individual atom, in the above example, there is a probability of 50% of decaying within 5000 years, a probability of 75% of decaying within 10,000 years, etc.
