Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus., Rutherford's atomic model Atomic experiment of Lord Ernest Rutherford In 1910, the New Zealand physicist Ernest Rutherford put forward the idea that the positive charges of the atom were found mostly in its center, in the nucleus , and the electrons ( e -) around it..

However, because of its simplicity, and its correct results for selected systems see below for application , the Bohr model is still commonly taught to introduce students to quantum mechanics or energy level diagrams before moving on to the more accurate, but more complex, valence shell atom. Atomic number - indicates the number of protons and defines the element (atomic number 6 is always carbon, atomic number 7 is always nitrogen etc.). Mass number - equals the total number of neutrons and protons in the nucleus of an atom for the most common isotope this
