Question

Which of the following increases the ratio?

Both β+ and β– decay
Only β– decay
Neither β+ nor β– decay
Only β+ decay

Answer 1

Only β+ decay

Step-by-step explanation:

In positron emission, a proton is converted into a neutron and a positron. An anti neutrino is a particle that serves the purpose of balancing the spins.

During positron emission, the mass number to the daughter nucleus is the same as that of the parent nucleus but the atomic number of the daughter nucleus is less than that of the parent nucleus by one unit.

Positron emission increases the neutron/proton ratio.
