Question

Compare the isotopes of Carbon.

Answer 1

Answer:

like and follow

Explanation:

Carbon-12 and carbon-14 are two isotopes of the element carbon. The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms. ... The number given after the atom name indicates the number of protons plus neutrons in an atom or ion. Atoms of both isotopes of carbon contain 6 protons.

Answer 2

Correct explanation:-

Carbon-12 and carbon-14 are two isotopes of the element carbon. The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms.

This is how this works. The number given after the atom name indicates the number of protons plus neutrons in an atom or ion. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons. A neutral atom would have the same number of protons and electrons, so a neutral atom of carbon-12 or carbon-14 would have 6 electrons.

Although neutrons do not carry an electrical charge, they have a mass comparable to that of protons, so different isotopes have different atomic weight. Carbon-12 is lighter than carbon-14.

Carbon Isotopes and Radioactivity

Because of the different number of neutrons, carbon-12 and carbon-14 differ in terms of radioactivity. Carbon-12 is a stable isotope; carbon-14, on the other hand, undergoes radioactive decay:

146C → 147N + 0-1e (half-life is 5720 years)
