Question

in what ways is an atom of carbon - 14 different than an atom of carbon - 12? carbon - 14 has a larger mass number carbon - 14 has more electrons carbon - 14 has more neutrons carbon - 14 has more protons

Explanation:

Carbon - 14 and carbon - 12 are isotopes. Isotopes have the same number of protons and electrons (as they are the same element, carbon with atomic number 6). The mass number is the sum of protons and neutrons. Carbon - 12 has a mass number of 12 and carbon - 14 has a mass number of 14, so carbon - 14 has a larger mass number. Since the number of protons is the same (6 for both), carbon - 14 has more neutrons (14 - 6 = 8 neutrons for carbon - 14 and 12 - 6 = 6 neutrons for carbon - 12).

Answer:

A. carbon - 14 has a larger mass number, C. carbon - 14 has more neutrons
