​A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14
Ede4ka [16]

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
