![]() I would encourage you to explore further. Each orbit or shell has a fixed energy and these circular orbits are known as orbital shells. looking for relationships in a meaningful way. Postulates of Bohr's Model of an Atom In an atom, electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells. 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. A Bohr model of a chlorine atom shows a nucleus surrounded by three concentric rings. This is because the electron can exist in many energy levels. 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. Bohr proposed that electrons do not radiate energy as they orbit the nucleus, but exist in states of constant energy that he called stationary states. We have carefully curated multiple quizzes with varying difficulty levels for a well-rounded practice session. Following the discoveries of hydrogen emission spectra and the photoelectric effect, the Danish physicist Niels Bohr (1885-1962) proposed a new model of the atom in 1915. ![]() ![]() When the electron moves from one allowed orbit to. We have quizzes covering each and every topic of Physical Chemistry and other concepts of Chemistry. Bohr tells us that the electrons in the Hydrogen atom can only occupy discrete orbits around the nucleus (not at any distance from it but at certain specific, quantized, positions or radial distances each one corresponding to an energetic state of your H atom) where they do not radiate energy. Now, the energy of the photon emitted from any element does not depend on the number of electrons in the atom. Solve these Bohrs Model of an atom questions and sharpen your practice problem-solving skills. 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. Here is my answer, but I would encourage you to explore this and similar questions further. ![]()
