Question

One difference between carbon-12 (12/6C) is that carbon-14 (14/6C) has

a) two more electrons than carbon-12.
b) two more neutrons than carbon-12.
c) two more protons than carbon-12.
d) two more electrons and two more neutrons than carbon-12.
e) two more protons and two more neutrons than carbon-12.

Answer 1

Carbon-14 has two more neutrons than carbon-12.

Step-by-step explanation:

Carbon-14 (14/6C) differs from carbon-12 (12/6C) in having two more neutrons than carbon-12. The atomic number of carbon is 6, which means that it has 6 protons. Both carbon-12 and carbon-14 have 6 protons, but carbon-14 has 8 neutrons while carbon-12 has 6 neutrons.
