This question already has an answer here:
I am a highschooler who eventually wants to deeply understand the properties of elements and compounds etc. I have been dabbling in some Chemistry books lately but I find them a bit superficial, and thus I have come to realize that I need a good understanding of Physics. What branches of Physics are the most related to these questions? I think they are Quantum and Solid State Physics but I am not sure. And what are the prerequisites for these branches of Physics? Books definitely do not look beginner-friendly.
I am aware that achieving a real understanding of these subjects is very hard but you have to start somewhere, right? I was actually thinking to major in something related to Chemistry, but as I said I have been disillusioned and now I think I will major in something related to Physics (And I enjoy Physics as well).
