WebBohr's first postulate was that an electron in an atom could revolve in certain stable orbits without the emission of radiant energy, contrary to the predictions of electromagnetic theory. According to this postulate, each atom has certain definite stable states in which it can exist, and each possible state has definite total energy. WebThe Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. Bohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. crystal palace park sunday marketWebBohr's model of the atom was prepared by Neil Bohr in 1915. Rutherford's atomic model began to be transformed. The Rutherford model introduces the nuclear atom model, in which he explains that the nucleus (well-charged) is surrounded by poorly charged electrons. Bohr modified this model of atomic structure by explaining that electrons … dyckman welfare center address
