Chapter 9, Problem 18P

Interpretation Introduction

Interpretation:

Consider Phosphorus-29, which is a positron emitter. Write nuclear equation and determine the product nucleus formed.

Concept Introduction:

During positron emission in a nucleus a proton gets converted to neutron releasing a positron and an electron neutrino.

Thus, there is a decrease in number of proton hence in atomic number. The mass number will remain the same as proton is being converted to neutron and mass number is sum of number of neutrons and protons.
