Why is the atomic model and theory subject to change?
4 answers
Because it's only a theory. If other information becomes available it could be changed.
Because there is still information that we don't know about atoms and info can change based on that. For example, a while ago, "there was news about a suspected Tetraneutron, a subatomic particle consisting of 4 neutrons clustered together, which defied our understanding of an atom and its constituents. So, clearly there is always something popping up for us to understand about atoms."
Thank you for these answers Snowflake and Dr. Bob! They're a great help since my brain loves going on vacation whenever I pick up a book, lol
No problem. My brain can be like that too sometimes :)
