Carbon 12 atomic number 6

Therefore one atom of carbon, isotopic mass 12, equals 12 u, or, 1 u = 1 / 12 th the mass of one atom of the carbon-12 isotope. Note that for the standard nuclide notation, , the top left number is the mass number (12) and the bottom left number is the atomic/proton number (6). Atomic number is often symbolized with the letter Z and is shown as a numerical subscript to the left of its chemical symbol. For example, the letter C preceded by a superscript number 12 and a subscript number 6 indicates a carbon atom of atomic mass 12 and atomic number 6, the difference being equal to the number of neutrons present in the nucleus. Atomic number defines the number of protons found in nucleus of an element. The total number of protons and neutrons (found in nucleus) is calculated as the atomic mass number. The following table illustrates the some of the significant elements with their atomic number, atomic mass, and symbols −

Carbon-12 and carbon-13 are stable. Carbon-14 is used for radioisotope dating of organic material. A total of 15 isotopes of carbon are known. The element name carbon comes from the Latin word carbo, which means coal. The element symbol for atomic number 6 is C. Carbon is among the...Sometimes they are referred to as Carbon-14 or Carbon-12. All isotopes of carbon have the same number of protons, but their number of neutrons can differ. Atomic mass is the weighted average of the isotopes of a particular element. For example ~99% of carbon is Carbon-12 and ~1% is Carbon-14. Atomic number definition is - an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table.
