Answer:
Oxygen has 8 neutrons
Explanation:
We know that cause the atomic number says how many protons does the element has, so in this case is eight, and in the mass number, we have the number of protons+neutrons, in this case is 16. Then, as we know that oxygen has eight protons with the atomic number, we would do 16-8 protons= 8 neutrons.
Check: Atomic number is 16= 8 protons + 8 neutrons
