Explanation The general reaction for positron decay is: a Z X → a Z − 1 X + 0 1 e Where A is mass number, z is atomic number (number of protons), and x is the symbol of element . Positron is an elementary particle that has the same mass and opposite charge to that of an electron. When an element loses a positron, a proton is transformed into a neutron in the nucleus of the parent radioactive element. The resulting nuclei will have an atomic number one unit lower than the original nucleus. There is no change to the atomic mass. Neon-19 has 10 protons (atomic number) and 9 neutrons in it. Atomic mass = number of protons+number ofneutrons = 19. When it decays by positron emission, the resultant product nuclei will have, proton count of 10-1 = 9

Question

Chapter 9, Problem 9.71P

Interpretation Introduction

Interpretation:

Products formed after positron emission from neon-19 and sodium-20 is should be determined.

Concept Introduction:

When an atom on undergoing radioactive decay release a positron and electron neutrino due to conversion of the proton inside a radionuclide nucleus into a neutron then such type of radioactive decay is said to be positron emission.
