What kind of nuclear decay occurs within most smoke detectors?
Many smoke detectors use Americium-241, which emits alpha rays, to keep air ionized.
Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
What actually decays in radioactive decay?
The nucleus of the atom decays, and in the process, the nucleus transforms into another element, or into an isotope or isomer of the same element. In radioactive decay, the nucleus always emits some kind of particle(s). It is the high-energy emission of these particles that we call radiation. There are many different types of radioactive decay:Alpha decay results in the emission of an alpha particle (two neutrons and two protons)Beta decay results in the emission of a beta particle (an electron or a positron)Neutron decay results in the emission of a neutronProton decay results in the emission of a protonGamma decay results in the emission of a gamma particle (a photon)Neutrino decay results in the emission of a neutrino or antineutrinoIn some cases, a combination of the above emissions takes place. For example in double beta decay, a single nucleus emits two electrons and two antineutrinos in the same event.
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 does the process in which an unstable atomic nucleus emits charged particles or energy or both?
In the process of radioactive decay an unstable atomic nucleus emits energy to get closer to a state of stability. Whether this energy is emitted in particles, electromagnetic radiation, or both depends on which decay paths are available to the nucleus and which decay paths are forbidden to the nucleus by Quantum Mechanics.Some of the decay processes are:alpha - energy is released in the momentum of the ejected alpha particle (helium nucleus)beta - energy is released in the momentum of the ejected electron or positron (and the hard to detect neutrino)gamma - energy is released as electromagnetic radiation (gamma ray photon)spontaneous fission - energy is released in the momentum of the ejected fission product atoms and the ejected neutrons
The nuclear reaction for the emission of gamma particle from cobalt 60?
Cobalt-60m decays by emitting a gamma particle. This changes neither the atomic number nor the isotope number, since no nucleons are lost. The gamma particle has an energy of 58.59 keV. The resulting atom is Cobalt-60.
What is the nuclear decay for beryllium?
Beryllium undergoes alpha decay, where it emits an alpha particle to form a new nucleus. This process transforms beryllium into a different element with two fewer protons.
What are the nuclear equations for the following processes bismuth 214 undergoes b-minus decay potassium-38 undergoes b-plus emission plutonium-242 emits radiation?
Bismuth-214 undergoes beta-minus decay: 214Bi --> 214Po + e^- Potassium-38 undergoes beta-plus emission: 38K --> 38Ar + e^+ Plutonium-242 emits radiation: No specific nuclear equation as "emits radiation" is a general statement.
How uranium effect your environment?
Uranium undergoes radioactive decay and emits alpha particles which can damage tissue.
Any process where the nucleus emits particles is called?
radiation
Determine what type of decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231?
Alpha decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231. In alpha decay, a nucleus emits an alpha particle (two protons and two neutrons) to transform into a nucleus with a lower atomic number.
What is the process that allows the nucleus of Radium to become stable?
Nuclear decay.
Which particle is emitted from a hydrogen-3 nucleus when it undergoes radioactive decay?
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
When bismuth 214 emits a positron the remaining daughter nucleus is what?
When bismuth-214 emits a positron, it undergoes beta-plus decay to produce polonium-214. This decay process involves the conversion of a proton into a neutron, releasing a positron and a neutrino.
When the nuclide astatine-218 undergoes alpha decay?
When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.
If cobalt-60 emits a gamma ray what is the product?
When cobalt-60 emits a gamma ray, it remains as cobalt-60. The emission of a gamma ray does not change the identity of the cobalt-60 isotope.
Is an input of energy required in order for nuclear decay to happen in an atom?
No, an input of energy is not required for nuclear decay to happen in an atom. Nuclear decay is a spontaneous process that occurs when an unstable nucleus emits particles or energy to become more stable.
