However, his model worked well as an explanation for the emissions of the hydrogen atom, but was seriously limited when applied to other atoms. Moving up the ladder increases your potential energy, while moving down the ladder decreases your energy.īohr's work had a strong influence on our modern understanding of the inner workings of the atom. Physics (1061802) Main content: The Bohr Atomic Model (1747417) The Bohr Atomic Model. As you move up or down a ladder, you can only occupy specific rungs and cannot be in the spaces in between rungs. Liveworksheets transforms your traditional printable worksheets into self-correcting interactive exercises that the students can do online and send to the teacher. An everyday analogy to the Bohr model is the rungs of a ladder. Bohrs model calculated the following energies for an electron in the shell, n. In this study, this consideration is translated by preparing a tutorial worksheet for Bohrs Atomic Model according to the suggestion of three learning levels of chemistry. The electron is not allowed to occupy any of the spaces in between the orbits. The orbits that are further from the nucleus are all of successively greater energy. The ground state of the hydrogen atom, where its energy is lowest, is when the electron is in the orbit that is closest to the nucleus. When the electron is in one of these orbits, its energy is fixed. It accounts for a wide range of physical phenomena, including the existence of discrete packets of energy and matter, the uncertainty principle, and the exclusion principle.Īccording to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits. This is a theory based on the principle that matter and energy have the properties of both particles and waves. This was the basis for what later became known as quantum theory. When the energy is removed, the electrons return back to their ground state, emitting a corresponding amount of energy-a quantum of light, or photon. De Broglie demonstrated that electrons had wave-like properties in addition to particle-like properties. Multiple representations of the varying theories of atomic structure. Metals lose electrons and nonmetals gain electrons.
