Final answer:

Positron emission involves the emission of a positron from the nucleus, converting a proton into a neutron and a positron, as seen in the decay of carbon-11 to boron-11.

Explanation:

Positron emission is a type of radioactivity where a positron is emitted from the nucleus, converting a proton into a neutron and a positron. An example is the decay of carbon-11 to boron-11 in positron emission. This process does not change the mass number but decreases the atomic number by 1.
