Using the periodic table determine the number of neutrons in O that has an atomic mass of 16

1 answer:

7 0

You will find that the atomic weight of oxygen is about 16. Since the weight of the protons and neutrons is about 1 (the electrons weigh almost nothing compared to protons and neutrons) and we know we have 8 protons in the nucleus, we can calculate the number of neutrons by subtracting 8 from 16 (16 - 8) which equals 8.
