Question

question 1 1 p why has the model of the atom changed over time? ○ the model has actually never changed. ○ the model changed because we can change it every day. ○ the model has changed based on new experiments and new findings that all built on one another. ○ the model of the atom has devolved to the point where it is now only a sphere, with no nucleus.

Explanation:

• Option 1: Incorrect, as atomic models (like Dalton, Rutherford, Bohr) have changed over time.
• Option 2: Incorrect, changes aren’t arbitrary daily changes but based on scientific progress.
• Option 3: Correct, atomic models evolve as new experiments (e.g., gold foil experiment, quantum experiments) and findings build on previous work.
• Option 4: Incorrect, modern atomic models (quantum mechanical) aren’t simple spheres without a nucleus.

Answer:

C. The model has changed based on new experiments and new findings that all built on one another.
