Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, <u>all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons</u>.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, <u>it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different</u>. Hence, the correct option is B
