well the mass number is actually 12. because the ATOMIC MASS is 12.011. and to find the mass number you must round the atomic mass to the nearest WHOLE NUMBER. 12.011 rrounded to its nearest whole number would be 12. and to find the number of neutrons you must subtract the ATOMIC NUMBER (which is 6) from its mass number. 12-6=6. so carbon has 6 neutrons. carbon also has 6 protons, as well as 6 electrons.
The mass number of a carbon isotope is the sum of the number of protons and neutrons in its nucleus. Since carbon has 6 protons, an isotope with 7 neutrons would have a mass number of 13 (6 protons + 7 neutrons = 13).
Since carbon 13 is an isotope of carbon with a mass number of 13, it has 13 nucleons (protons and neutrons). The number of electrons in a neutral carbon 13 atom is equal to the number of protons in its nucleus, which is 6. Therefore, in 9 g of carbon 13, there are Avogadro's number of carbon 13 atoms, each with 6 electrons, totaling approximately 3 x 10^23 electrons.
The atomic mass of elemental Carbon is 12.011. There are two stable isotopes with differing mass numbers: 12 (98,9%) and 13 (1,1%) and one semi-stable C isotope nr. 14 (half-life time 5730 yr.)
Carbon: C-13 isotope, stable, 1.1% of all natural occurring carbon (98.9% C-12) Atomic number: 6 (number of protons in nucleus) Atomic mass: 13.0033 a.m.e. Mass number: 13 (= 6 protons + 7 neutrons in nucleus) Nonmetal
um...13 Carbon 13 is not a radioisotope. It isn't radioactive. It's atomic number is 6 and atomic mass is 13 The exact mass is 13.003355 according to http://www.sisweb.com/referenc/source/exactmas.htmThe atomic mass of carbon 13 is 13.0033548378
The mass number of carbon is 13, so the nucleus contains 6 protons and 7 neutrons. The total number of protons and neutrons in the nucleus is 13.

The mass number of a carbon isotope is the sum of the number of protons and neutrons in its nucleus. Since carbon has 6 protons, an isotope with 7 neutrons would have a mass number of 13 (6 protons + 7 neutrons = 13).
Carbon-13 has 6 protons because the element is carbon. Since the atomic number for carbon is 6, it tells us the number of protons. Carbon-13 has 7 neutrons because to get the number of neutrons you subtract the atomic number from the mass number, which is 13.
Since carbon 13 is an isotope of carbon with a mass number of 13, it has 13 nucleons (protons and neutrons). The number of electrons in a neutral carbon 13 atom is equal to the number of protons in its nucleus, which is 6. Therefore, in 9 g of carbon 13, there are Avogadro's number of carbon 13 atoms, each with 6 electrons, totaling approximately 3 x 10^23 electrons.
Carbon 13 has 7 neutrons.The atomic mass represents the total number of protons and electrons. Carbon atoms have 6 protons. Therefore, the atomic mass being 13, it has 7 neutrons.
There are three isotopes of carbon with mass numbers 12 (which is more than 99% of existing carbon), 13, and 14 (which is radioactive).
Three isotopes of carbon are carbon-12, carbon-13, and carbon-14. Isobars of carbon are elements with the same mass number, such as nitrogen-14 and oxygen-14.
The atomic mass of elemental Carbon is 12.011. There are two stable isotopes with differing mass numbers: 12 (98,9%) and 13 (1,1%) and one semi-stable C isotope nr. 14 (half-life time 5730 yr.)
To draw two isotopes of carbon, you would start with the atomic symbol "C" in the center of a circle. For carbon-12, which has a mass number of 12, you would write "12" as a superscript before the atomic symbol "C." For carbon-14, with a mass number of 14, you would similarly write "14" as a superscript before the atomic symbol "C." This notation helps differentiate between the isotopes based on their respective mass numbers.
