量子力学モデル(quantum mechanical model) とは何か簡単に概要だけでも教えてもらえませんか？ 高校何年生でやるのかだけでも構わないので教えてください🙇‍♂️

The Bohring World of Niels Bohr In 1913WBohr proposed that electrons are arranged in concentric circular paths or orbits around the nucleus. Bohr answered in a novel way why electrons which are attracted to protons, never crash into the nucleus. He proposed that electrons in a particular path have a fixed energy. Thus they do not lose energy and crash into the nucleus. 7カje energy /eve/ of g/) e/ecro7 5 太e 7eg/O7 g7Ounの のe 70C7eus Were た5がeルfo pe. These energy levels are like rungs on a ladder, lower levels have less energy and work. The opposite is also true if an electron loses energy it falls to a lower level. Also an electron can only be found rungs of a ladder. The amount of energy gained or lost by every electron is not always the same. Unlike the rungs of a ladder, the energy levels are not evenly spaced. 4 gug/fg77 O7 ene79y 75 妨e 977Ou7た Oげ ener9y ee0eg ro 77oVe 7 e/ecfron廊O77 745 prese7t _ene/rgy 7eve/ 7O je exf jgカer oe or to make a quantum leap- The Quantum Mechanical Model Like the Bohr model, the ggg74777 776c7g77Co/ 777Oe/ leads to gugn67ze9 energy levels for an electron. However the Quantum Mechanical model does not define the exact path an electron takes around the nucleus. It is concerned with the likelihood of finding an electron in a certain position.
