hello, I have come across "quantum physics" during the curriculum of an Inorganic chemistry course. and since the topic is too broad, I'm confused a bit about what exactly do I need to know ( or to which extent should I learn about this theory). we are studying the historical development of the atom model , and quantum mechanics comes along as the reason to why Bohr's model was no longer accepted. my question is what would be enough to know about the theory , to serve this study aim ( the development of the atom model). Thanks in advance.
