Bohr's model of the atom can be described as follows An atom is made up of three particles protons, electrons, and neutrons Electrons have a negative charge, protons have a positive charge and neutrons have no charge Due to the presence of an equal number of negative electrons and positive protons, the atom, on the whole, is electricallyThe wave equation did not only give the correct energy levels for the hydrogen atoms but was also kinda useful in atoms with more than one electron This math equation described the details of atomic behavior became known as the Wave Mechanical Model 4 The Bohr Model in 1913 Neils Bohr suggested putting the quantum theory to the Rutherford model Nelis Bohr's new model
The BohrSommerfeld model is an extension of the Bohr model It explains the distribution of electrons within the shells The weaknesses of the Bohr model could be partially eliminated by the physicist Arnold SommerfeldIn addition to the already introduced shells by Bohr, Sommerfeld further introduced subshells (also referred to as orbitals)Bohr's Model of the Atom In 1913, Neil Bohr proposed a theory to explain the stability of an atom, where electrons revolved around the nucleus at certain energy levels Each orbital had a different radius and electrons revolving in a particular orbit did not radiate energy This happened even if the electron had accelerated motion around the nucleus Bohr put forth some postulates thatAccording to Bohr's model of the atom, electrons orbit about the nucleus much like the way planets orbit the sun Different energy levels are associated with the different orbits The diagram below shows the Bohr model for fluorine The nucleus of fluorine has 9 protons Surrounding the nucleus of fluorine is 9 electrons The electrons arrange themselves in 3 orbits In the first orbit,
Niels Bohr, a Danish scientist, explained this line spectrum while developing a model for the atom The Bohr model shows that the electrons in atoms are in orbits of differing energy around the nucleus (think of planets orbiting around the sun) Bohr used the term energy levels (or shells) to describe these orbits of differing energyBohr's model of the hydrogen atom is based on three postulates (1) an electron moves around the nucleus in a circular orbit, (2) an electron's angular momentum in the orbit is quantized, and (3) the change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon Bohr's model is semiclassical because Follow Us To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number After that, place the neutrons and the protons in the nucleus, and draw the electrons in their designated shells Find the number of electrons, protons and neutrons
