    From the example of carbon, carbon only exists in the isotopes carbon-12, carbon-13, and carbon-14. Carbon-12 is by far the most common isotope of carbon. The calculation of the atomic mass of ...

  3. What is the atomic number of carbon-14? - Socratic

    socratic.org/questions/what-is-the-atomic-number-of-carbon-14

    The bottom number of the atom is the atomic number which is based on the number of protons. The 14 is the total mass of the atom. Carbon 14 has 6 protons and 8 neutrons for a total mass of 14

    The atom has 6 "protons", and 6 "neutrons". You specified a carbon atom. By definition, the C atom has 6 protons, 6 positively charged nuclear particles, in its nucleus. You further specified the ""^12C isotope. There must be 6 neutrons, 6 neutrally charged, massive particles in its nucleus. If it's a carbon atom, the number of protons cannot change (why not?), but the number of neutrons in ...

  5. What is the isotope notation for carbon-14? - Socratic

    socratic.org/questions/what-is-the-isotope-notation-for-carbon-14

    ""_6^14 C Isotope notation is of the form ""_Z^A X where Z is the atomic number (number of protons), A is the mass number (sum of protons and neutrons), and X is the element. In Carbon-14, 14 is the mass number (sum of protons and neutrons). This is our A. Carbon has the atomic symbol C, and it has 6 protons. This is the atomic number, or A. Thus, the isotope notation for Carbon-14 is ""_6^14 ...

    From the periodic table, we see that the atomic number (number of protons) for the element carbon is #6#. The name carbon-14 tells us that this isotope's mass number is #14#. The chemical symbol for carbon is #"C"#. Now write the isotopic notation for carbon-14. #""_6^14"C"# We can determine the number of neutrons as #14-6=8# neutrons. Example 2.

    See Below Carbon has 3 isotopes. Carbon-12, Carbon-13, and Carbon-14 All of them have an atomic number of 6, which means all of them have 6 protons (if they had different numbers of protons, they'd be different elements). Since they all have 6 protons, in their elemental forms, they all have 6 electrons, too. Carbon-12: Atomic number: 6 Mass number: 12 protons: 6 electrons: 6 neutrons: 6 ...

    And so for #""^1H#, the mass number is simply 1; for #""^2H#, the mass number is simply 2; for #""^3H#, the mass number is simply 3. The isotopes contain #"0, 1, 2 NEUTRONS"# respectively. Most of the heavier atoms have a range of isotopes, and the quoted atomic mass on the Table is the weighted average of the isotopic masses..

  9. What is the mass number for carbon? | Homework.Study.com

    The mass number for carbon is 12amu. The mass number is the sum of the number of protons and the number of neutrons in an atom.

  10. How do you calculate the atomic mass of carbon? - Socratic

    socratic.org/questions/how-to-calculate-the-atomic-mass-of--carbon

    The term "atomic mass" refers to the mass of a single atom. The mass of a single atom of carbon-12 is defined as exactly 12 u. The term atomic mass is also often used (though technically, incorrectly) to refer to the average atomic mass of all of the isotopes of an element. This second definition is actually the relative atomic mass of an element — a single average value of the element's ...
