Question

After James Chadwick discovered the neutron, atomic theory expanded to include isotopes. Isotopes have many practical uses. For example,
scientists use the relative amount of carbon-12 to carbon-14 in ancient bones to determine how old they are.

How many neutrons are in an atom of Carbon-147
A 2
B 6
C 8
D 14

Answer 1

Answer:

The answer is C which is 8 neutrons

Explanation:

This is because all carbon isotopes have 6 protons in their nucleus. Carbon 14 have 2 extra neutron aside from only having 6. So 6 protons + 6 neutrons + 2 more extra makes 14 which makes it Carbon - 14. I hope this makes sense.
