Write a balanced nuclear equation for the positron decay of tantalum-165. Rhenium (Re), with a mass number of 180 and an atomic number of 75, decays by emission of an alpha particle. Identify the product of the nuclear reaction by providing its atomic symbol (5 pts), mass n

2005年11月7日 · In positron emission, a proton is converted into a neutron, a positron, and a neutrino: p --> n + e + v this conversion occures only in a nucleus, because this process consumes energy (the neutron and positron have a higher mass than the proton). The energy needed is twice the rest mass energy of the electron: 1.022 MeV.

2012年6月18日 · A stray neutrino cannot cause positron decay (violation of electron charge) - only a stray antineutrino could. But if it does, the whole energy of the neutrino goes to the positron. Actually, positron decay is spontanous just like beta decay, and involves emission of a new neutrino completely irrespective of the presence of any antineutrinoes.

Positron decay is a type of beta decay in which a positron and a neutrino are emitted from an atom. A positron is a type of subatomic particle with...

Answer to If Magnesium-21 undergoes beta positron decay, I. To find the product of the beta positron decay of Magnesium-21, identify that in the beta positron decay process, a proton is converted into a neutron with the emission of a positron and a neutrino, and observe the change in atomic number and mass number resulting from this conversion.

The carbon isotope " C undergoes B + (positron) decay. The atomic mass of C is 1 1. 0 1 1 4 3 3 u. (a) How many protons and how many neutrons are in the daughter nucleus produced by this decay? (b) How much energy, in MeV, is released in the decay of one " C nucleus

Positron Decay: Positron decay is also known as beta plus decay. Similar to beta minus decay, one nuclear particle is transformed into the opposite type of nuclear particle and a beta particle is emitted. However, positron decay changes a proton to a neutron and ejects a positron. Answer and Explanation: 1

1. Positron decay/electron capture 2. Neutron decay 3. Proton decay 4. Beta decay 5. Alpha decay; Predict a likely mode of decay for each of the following unstable nuclides. *a. Rh-92: beta decay or positron emission *b. Ga-60: beta decay or positron emission *c. S-27: beta decay or positron em; What mode of decay is probable for 41/18 Ar ?

Nuclear Decay: Nuclear decay happens in large atomic nuclei or during a nuclear reaction like fission. When nuclear decay happens, there is a release of energy as electromagnetic waves and high-energy particles.
