What radionuclide decays to Br-73 by positron emission?
Work backwards. Positron emission means (essentially) a proton decayed into a neutron/positron pair. The mass number remains the same, but the atomic number goes down one to Bromine. Krypton has an isotope that fits this bill.
What is the nuclear decay equation for copper 64?
Cu decays by either negative or positive beta emission. The equation for the negative beta decay of 64Cu is: 2964Cu --> 3064Zn + -10e where -10e represents a negative beta particle or electron. The equation for the positive beta decay of 64Cu is: 2964Cu --> 2864Ni + 10e where 10e represents a positive beta particle or positron.
Do radioactive emissions have a charge?
Depends on what type of radioactive decay you are talking about. Beta decay (electron or positron) will have a charge, while alpha decay will not. Beta decay can either be positron decay or electron decay. Positron will result in the parent to have the same atomic mass but a different atomic number. The atomic number will be one less than that of the parent. Meaning one proton will decay into a neutron and a positron, which is a positively charged particle. Electron decay results in the parent gaining a proton while the atomic mass stays the same. A neutron decays into a proton and an electron and the electron is emitted with a negative charge. Alpha decay, however, results in the emission of a neutral helium particle. Gamma decay results in the same parent with no loss of charge or atomic number and gives off a high energy photon called a gamma particle.
What is the nuclide produced when uranium 238 decays by alpha emission?
For decays by alpha emission use the general formula: A/Z X --> 4/2 He + A-4/Z-2 Y *Where A is atomic mass and Z is atomic number. So for U-238 238/92 U --> 4/2 He + 234/90 Th
What is the beta decay for copper-66?
Cu decays by either negative or positive beta emission. The equation for the negative beta decay of 64Cu is: 2964Cu --> 3064Zn + -10e where -10e represents a negative beta particle or electron. The equation for the positive beta decay of 64Cu is: 2964Cu --> 2864Ni + 10e where 10e represents a positive beta particle or positron.

What is the inert gas daughter product of the radioactive isotope K-40?
Argon-40 Naturally occurring K-40 with a half-life of 1.25×109 years, decays to stable Ar-40 (11.2%) by electron capture or positron emission.
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 particle is emitted when Na-20 decays to Ne-20?
A positive electron (positron) is emitted.
Would an atom of radioactive gold be more likely to decay by alpha emission or beta emission?
Gold never decays by alpha emission, it either decays by -beta, +beta, K capture, or gamma emission depending on isotope.Natural gold is isotopically pure gold-197, which is stable.
How isotopes produced?
An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.
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 is the product of a beta emission from strontium-90?
Yttrium-90 "the slash is important"
What happens when californium 251 decays into curium 247?
Californium-251 decay by alpha emission.
What are the 4 types of radiation and what does each type do to the nucleus?
Usually with the '4 types of radiation' it is referred to:- alpha radiation (emission of an alpha particle = a helium nucleus = 2 neutrons + 2 protons):Hence for the emitting nucleus the mass number decreases by 4 and the atomic number by 2.- beta-minus radiation (emission of a beta- particle = an electron)Hence for the emitting nucleus the mass number remains the same and the atomic number increases by 1 (a neutron decays into a proton and beta- radiation)- beta-plus radiation (emission of a beta+ particle = a positron)Hence for the emitting nucleus the mass number remains the same and the atomic number decreases by 1 (under the addition of energy a proton decays into a neutron and a positron)- gamma radiation (emission of high energetic photons)The emitting nucleus doesn't change its mass number and atomic number,but it jumps from a higher energy level to a lower energy level.
How is isotope produced?
An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.
Which radioactive isotope is used to monitor the thickness of metal strips?
Caesium-137 as it decays by beta emission.
