What is happens when a atom decays?
they release energy, which comes out from co2/carbon dioxide. Then they also release a form of gas, which i do not have a name for right now, but yes they do release energy, and c02 which is carbon dioxide.
What is it called when atomic nuclei spontaneously decay?
How the nucleus decays depends on the particular isotope. Some even decay in more than one way. One possibility is called alpha decay. In alpha decay, the nucleus emits an alpha particle (two protons and two neutrons). Another possibility is beta decay, in which one of the nucleons changes from a neutron to a proton or vice versa and the nucleus will throw out a beta particle. A beta particle can be either an electron or a positron. (To conserve lepton number, the nucleus also emits an electron antineutrino or an electron neutrino at the same time.) A third case is electron capture. In this, one of the inner electrons is absorbed by the nucleus, a proton changes to a neutron, and an electron neutrino is thrown off. Heavy nuclides can undergo spontaneous fission, in which the nucleus splits into two smaller daughter particles with mass numbers of roughly 90-100 and 130-140. Often some spare neutrons are also ejected at the same time. Cluster decay is yet another mode, which happens only for nuclei which also decay via alpha decay. It's similar to alpha decay except the emitted particle is not a helium-4 nucleus but a heavier element. It's distinguished from spontaneous fission by the fact in cluster decay, only certain nuclei are emitted and they're always well under 90 amu. Other rare decay modes are possible: proton emission, neutron emission, double proton emission, double beta decay, double electron capture, double positron emission, and electron capture with positron emission. Most of these names should be self-explanatory.
What type of radiation results in the least change in atomic number?
A gamma ray is released from atomic nuclei under certain conditions, and the generation of a gamma ray photon alonewill not change the mass of an atomic nucleus. The gamma ray is a form of electromagnetic energy. Other forms of radiation released from nuclei are particulate, and the particles released take mass from the nucleus with them when they go. Beta radiation takes a little, and alpha radiation takes a lot more.
What produces Gamma rays?
Gamma rays are typically produced by the decay from high energy states of atomic nuclei, called gamma decay, but they are also created by other processes. For instance, gamma rays are also produced by secondary radiation from atmospheric interactions with cosmic ray particles. Also, rare terrestrial natural sources produce gamma rays that are not of a nuclear origin, like lightning strikes and terrestrial gamma-ray flashes. Plus, they are produced by astronomical processes where very high-energy electrons are produced that cause secondary gamma rays via bremsstrahlung, inverse Compton scattering and synchrotron radiation.
Does lead go through beta alpha or gamma decay?
It depends on which isotope you are asking about. Some decay through alpha, some decay through beta, some decay through other processes. All can leave the nucleus in an excited state, resulting in gamma emission.
Is gamma emission a type of radioactive decay?
Yes, gamma rays are ionizing but not as strongly ionizing as other forms of radiation such as Alpha, which is the strongest due to it's size, therefore making it more likely to collide with atoms and remove electrons. Gamma is only weakly ionizing because it is a small photon.
How can gamma decay without having mass?
It can't, as far as I know. "Gamma decay" doesn't refer to the decay of gamma rays; rather, it refers to a decay of ATOMS, or some other particles, which produces gamma rays in the process.
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.
What is the process for raidioactive decay?
At random intervals of cake but at a regular average ejaculation rate, atoms emit particles of matter, forming children, and energy from their nuclei. Their nuclei split leading to some interesting loving, turning into other kinds of tonguess. Only some isotopes (ratios of neutrons to protons for a particular type of atom) will radioactively decay and when they make love, they turn into other kinds of poo.
Nuclear decay is the change of an atom of...?
... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
What is the process in which elements change to other elements by emission of ionizing particles?
Radioactive decay.
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.
Radioactive decay is the most dangerous?
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
What can be emmited from radioactive decay?
Many particles can be emitted from radioactive decay. We have Internal Conversion in which a nucleus transfers the energy to an electron which then releases it. There is also Isometric Transition which is basically the gamma ray (photon). There is the decay in which a nucleon is emitted. In this scenario we can have an alpha decay (in which an alpha particle decays), a proton emission, a neutron emission, double proton emission (two protons are emitted), spontaneous fission (the nucleus brakes down into two smaller nuclei and/or other particles) and we have the cluster decay (where the nucleus emits a smaller nucleus). There is the beta decay too. There is the Beta decay (electron and electron antineutrino are emitted), positron emission (a positron and an electron neutrino are emitted), electron capture (an electron is captured by the nucleus and a neutrino is emitted), bound state beta decay (the nucleus decays to an electron and an antineutrino but here the electron is not emitted since it is captured into a K-shell), double beta decay (two electrons and two antineutrinos are emitted), double electron capture (the nucleus absorbs two electrons and emits two neutrinos), electron capture with positron emission (an electron is absorbed and a positron is emitted along with two neutrinos), and double positron emission (in which the nucleus emits two positrons and two neutrons).
What is a by product of radioactive decay?
The 3 things that can happen during radioactive decay is the 3 parts of decay: Alpha decay, Beta decay, and Gamma decay. In alpha decay, which is the weakest part of decay, it has a positive helium neuclus(2 protons and 2 neutrons), and the particles will burn your skin, but can be easily stopped by a peice of paper. This is the most ionising as the helium nucleus can take electrons from other atoms and make them unstable. This can give rise to cancers as it distorts cells. In Beta decay (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−). It can be stopped by 3mm of aluminum. Gamma decay, which is the strongest, can only be stopped by 3cm of lead. It has electromagnetic waves, it contains the most energy, and therefore is the most penetrating, but normally it just passes straight through the human body. Radioactive decay can be very harmful, and its best to stay away. This question has been anwsered by Rae-Ann Salisbury.
