![]() Rutherford’s earlier model of the atom had also assumed that electrons moved in circular orbits around the nucleus and that the atom was held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electron. Of these isotopes, 12C has an abundance of 98.9. Carbon has two stable isotopes 12C and 13C. Therefore, a carbon atom will have two electrons in the first shell and four. This implies that it contains one proton, one electron and no neutrons (Total number of neutrons Mass number Atomic number) Carbon. That is, the number of electrons in carbon is 6. Carbon has 2 electrons in its first shell and 4 in its second shell. ![]() Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. Understand the structure of atom with Dalton’s, Thomson, Rutherford, and Bohr’s Atomic Model. How to Draw the Bohr-Rutherford Diagram of Carbon. ![]() In 1913, a Danish physicist, Niels Bohr (1885–1962 Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. ![]()
