Question

13C and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14C?

Answer 1

The nuclei number can only variable in the number of neutrons, as if we added more protons we would get another element, and adding or removing electrons would create a ion of the specific element.
So for the isotope:
\[_{6}^{14}C\]
We have 6 protons, 6 electrons and can you then guess how many neutrons it contain?

Answer 2

is it 7 neutrons
