## Step1: Identify the initial nuclei and the process### Positron emission involves a proton converting into a neutron, releasing a positron ( ) and a neutrino ( ). The atomic number decreases by 1, but the mass number remains the same.## Step2: Determine the resulting nuclei### For xenon-118 ( ), after positron emission, the resulting element will have an atomic number of 53 (iodine), but the mass number remains 118.### For manganese-50 ( ), after positron emission, the resulting element will have an atomic number of 24 (chromium), but the mass number remains 50.## Step3: Write the balanced nuclear equations### The balanced equations for the positron emission of xenon-118 and manganese-50 are:
