WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative. Even for an H atom in an excited state, the energy is negative, but it is less negative than for an atom in the ground state.

WebWhich statement is true of the quantum mechanical model, but not of the Bohr model? a. Electrons orbit the nucleus in simple circular orbits, just like planets orbit the Sun. b. The exact path that an electron follows within an atom cannot be specified. c. The electron is attracted to the nucleus of the atom. WebBohr's model had one significant drawback - they were only a 2-D diagram of the truth. In reality the actual model of the atom is the Sommerfield atom, where we see electrons travelling in an elliptical path around the nucleus, but in the xyz plane. In plain words, Bohr's model was a 2-D shape while Sommerfield's was a 3-D shape of an atom. Share
