Step-by-step explanation:
Positrons are often called positive electrons. They have the same mass and magnitude of charge as the electron but are of opposite sign. This means that they are positively charged while electrons are negatively charged.
In positron emission, a proton is converted into a neutron and a positron. The anti neutrino is a particle that balances the spins.
In electron capture, an electron is converted to a neutron. The anti neutrino is a particle that balances the spins.
When transmutation occurs by positron emission, the mass number of the of the parent nucleus is the same as mass number of the daughter nucleus but the atomic number of daughter nucleus decreases by 1 while the neutron/proton ratio increases.
When transmutation occurs by electron capture, the mass number of the of the parent nucleus is the same as mass number of the daughter nucleus but the atomic number of daughter nucleus decreases by 1 while the neutron/proton ratio increases.
