Answer
To determine the number of neutrons and protons in the isotope (^{16}O):
Identify the Mass Number: The mass number of (^{16}O) indicates it has 16 nucleons (protons + neutrons).
Determine the Atomic Number: Oxygen has an atomic number of 8, which means it has 8 protons.
Calculate the Number of Neutrons: Subtract the number of protons from the mass number:
Number of Neutrons=Mass Number−Number of Protons=16−8=8
Find the Correct Option: The correct row that shows 8 neutrons and 8 protons is option C.
