Write a nuclear equation for positron emission by each nuclide.
Here, we are going to write nuclear equations for positron emission by each nuclide.
Positron emission is similar to beta emission(splitting of a neutron into a proton and an accompanying electron.), but in this case, a proton becomes a neutron and an anti-matter electron, or antielectron. The latter is also called a positron because, although it resembles an electron in most ways, it has a positive charge.
P → n + e+
In nuclear equations for positron emission, the electron is written as either 𝛃+, e or e.
In positron emission, the radioactive nuclide changes into a different element, with an atomic number that is lower by 1 but the same mass number.
The atomic number of Co is 27. So, when Co-55 undergoes positron emission, a daughter nuclei with atomic number 26(Fe) is formed. The nuclear equation is:
Co → Fe...
