Question

Predict: During positron emission, a protonis transformed into a neutronand a positron, which is emitted.The positron will fly through space until it encounters an electron.How will positron emissionaffect the atomic number and mass number of the atom

Answer 1

See explanation

Step-by-step explanation:

A positron is also called a positive electron. It results from the transformation of a proton into a neutron.

When a nucleus decays by positron emission, the atomic mass of both the parent and daughter nuclei remain the same but the atomic number of the daughter nucleus decreases by 1 compared to that of the parent nucleus. The daughter nucleus is now found one place to the left of the parent nucleus in the periodic table.

This leads to an increase in the Neutron/Proton ratio.
