Detailed explanation-1: -Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes. The addition of even one neutron can dramatically change an isotope’s properties.
Detailed explanation-2: -A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes. For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus.
Detailed explanation-3: -Carbon-12 and Carbon-14 both contains the same proton number and electrons number. Atomic number is also same for both Carbon-12 and Carbon-14 that is 6.
Detailed explanation-4: -Carbon has two isotopes: 12C and 13C. Both show the same chemical features because of the same atomic number. But the mass of 13C is larger than that of 12C, because 13C has one more neutron.
Detailed explanation-5: -Answer and Explanation: Carbon-12 and carbon-13 differ as they have different amounts of neutrons and different mass numbers. Both carbon-12 and carbon-13, have same number of electrons and protons, that is, 6. Carbon-12 has 6 neutrons, while Carbon-13 has 7 neutrons in it.
