![]() Light of higher frequency has higher energy and shorter wavelength. The constant of proportionality h is known as Planck’s constant and has the value 6.626 × 10 –34 J s. I would encourage you to explore further.\] 2: The Bohr Model of the Hydrogen Atom (a) The distance of the orbit from the nucleus increases with increasing n. looking for relationships in a meaningful way. In this state the radius of the orbit is also infinite. We can, however, say that the more electrons there are in an atom, the greater the variety of photon energies there will be so this may be a link worth exploringĪs I say, you are asking a great question. as it switches from one energy level to another, then it emits / absorbs photons. Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The orbits are termed as stationary orbit. The outermost shell in the Bohr diagram of Oxygen contains 6 electrons that also called valence electrons. Electrons revolve around the nucleus in a fixed circular path termed orbits or shells or energy level. This nucleus is surrounded by two-electron shells named K-shell and L-shell. The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun. ![]() See all videos for this article Bohr model of the atom In the Bohr model of the atom, electrons travel in defined circular orbits around the nucleus. An early model of the atom was developed in 1913 by the Danish scientist Niels Bohr (18851962). This is because the electron can exist in many energy levels. The Bohr Model of Oxygen (O) has a nucleus that contains 8 neutrons and 8 protons. Britannica Quiz Matter and More Quiz How does Niels Bohr's atomic model work An overview of Niels Bohr's refinement of the Rutherford model. Hydrogen, for example, although the simplest atom, has a whole range of photon energies that it emits. The value of the energies of photons does depend on the available energy levels in the atom. Now, the energy of the photon emitted from any element does not depend on the number of electrons in the atom. OK: I would say that the periodic table tells us about the number of protons in an element and, therefore the number of electrons too. Valence electrons are the outermost electrons present in the outermost shell of an atom. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. ![]() The model was proposed by physicist Niels Bohr in 1913. Also check How to draw Bohr model of Sodium atom. The Bohr Model is a structural model of an atom. Here is my answer, but I would encourage you to explore this and similar questions further. Therefore, the electrons per shell for Sodium is 2, 8, 1, hence, we can say, based on the shell, the electronic configuration of the Sodium atom is 2, 8, 1.
