A marsupi ial is a type | 9f mammal. Their babies start to grow in a pouch on the th | Other Stomach, jike kangaroos. Tasmanian devils are night h unters. They | have dark fur。 a good sense of smell, and a strong bite. Theyre IS the biggest meat-eating marsupial in the world. Today these animal als are Tasmania's icon, but this wasnt always the case. In the early | 1800s, they were thought of as pests by the early European Settlers| So they hunted the Tasmanian devils. This led to a decline in th population. Currently, Tasmanian devils are on the endangereq | Species jist. To prevent their extinction, the Australian government started the “Save the Tasmanian Devil Program* in 2003 to monitor and assist Tasmanian devils in the wild. | There are numerous reasons for the dechne of the Tasmanian | devils, but the population started declining rapidly after the arrival ot a virus known as devil facial tumour disease in the mid-90s The Number of Tasmanian Devils 300000 100% 250000 9000 80% 200000 200000_6g% 170000 60% 150000 150000 47% - 117500 100000 15% 較 10% 拉 37500 ご55o0 0 l ma 1996 2000 2004 2006 2008 2010 2015 10

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.
