The diagram below shows how our understanding of the structure of the atom has changed over time.Based on these models, which statement correctly describes what has happened to the theory of atomic structure over time?*1 pointIt has remained constant and unchanged since its development.It has been completely rejected once new data show it to be false.It has been updated and modified based on the new data collected.It has remained basically intact but has been updated based on opinions and beliefs.SubmitClear form

In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson’s discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?Group of answer choicesNew evidence that supports a change prompts scientists to modify earlier theories.Scientists want to prove that the work of other scientists is wrong.So much information is available today that it is harder to focus research and disprove theories.Theories more than ten years old are usually out of date.
