Atomic Number of Carbon Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure. The chemical symbol for Carbon is C. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.
- James, carbon has 6 electrons and 6 protons. Remember that the positively charged protons and negatively charged electrons have to balance each other.
- Carbon has seven isotopes. In 1961 the International Union of Pure and Applied Chemistry adopted the isotope carbon-12 as the basis for atomic weights. Carbon-14, an isotope with a half-life of 5715 years, has been widely used to date such materials as wood, archaeological specimens, etc.
