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.

1、2の答えはなんでしょうか?お願いします。

英 癌に答えよ。 1. 次の英文を読み, yarious reasonS for the recent shortage of food on the world There are market。 One factor isS the extended drought* jn Australia,a major food exporter, This is almost certainly related to global warming. Another factor is the diversion of American corn and soybeans to biofuel production.。 Im 2007. over a quarter of US corn and a fifth of US soybeans were used for biofuels These trends coincided with an increase in the demand for food in China anq ーー India,ldue to economic growth, changing diets and increasing population。 At the に same time, farmland in many countries is being lost to urban development and Teson 1ana the amount of food which is produced is declining due to water shortages and, in China's case, to air and water pollution. Experts are now predicting a major global food crisis. Japan would seriously suffer from this problem when it comes to wheat and SMG which it depends heavily on imports to meet its needs. At the same tme 380.000 hectares of farmland are currently unused, due to an earlier program aimed at reducing rice surpluses. If these could be cultivated, they could help increase Japan's food security. Shortages are not the only concern with regard to food. ]apanese consumerSs also have to worry about the safety of the food they buy。 Many In 2007.a number of people were sickened by gyoz2 dumplings imported from China that were contaminated* mwith a banned pesticide. The mass media then drew attention to the fact that imports contain 則egal pesticides and food additives owing to staff shortages, only one tenth of all imported food was being inspected py quarantine oficers* among Which processed foods were not included。 The discovery』 in imported American beef of a material banned because of its ink t pk べM85(950)
