Answer

Explanation:

Step1: Identify the element

The atomic number (sub - script) is 6 for all isotopes. Atomic number determines the element, and the element with atomic number 6 is carbon.

Step2: Identify the meaning of the numbers

The numbers 12, 13, and 14 are the mass numbers. Mass number = number of protons + number of neutrons.

Step3: Determine protons and neutrons for each isotope

For an isotope, the number of protons is equal to the atomic number. The number of neutrons = mass number - number of protons.

  • For $^{12}_{6}C$: Protons (P+) = 6, Neutrons (N) = 12 - 6=6.
  • For $^{13}_{6}C$: Protons (P+) = 6, Neutrons (N) = 13 - 6 = 7.
  • For $^{14}_{6}C$: Protons (P+) = 6, Neutrons (N) = 14 - 6 = 8.

Answer:

a. Carbon b. Mass numbers c. 6, 6 d. 6, 7 e. 6, 8
