Question

Carbon-14 is a naturally-occuring, stable isotope that is commonly used is scientific studies as a tracer and to date artifacts. Using the periodic table, predict the number of electrons, neutrons, and protons in carbon-14.
A) Carbon-14 contains 7 electrons, 7 neutrons, and 7 protons.
B) Carbon-14 contains 6 electrons, 8 neutrons, and 6 protons.
C) Carbon-14 contains 6 electrons, 8 neutrons, and 7 protons.
D) Carbon-14 contains 7 electrons, 8 neutrons, and 9 protons.

Answer 1

Carbon-14 contains 6 electrons, 8 neutrons, and 6 protons. This isotope varies in the number of neutrons in the nucleus.

Answer 2

The answer is that there are 6 electrons, 8 neutrons, and 6 protons in carbon 14. The answer is then, B.
