Question

Knowledge of atomic structure has evolved over time. Thomson discovered that atoms contain electrons, Rutherford discovered that most of the mass of an atom is concentrated in its center, and Bohr discovered that electrons orbit the nucleus.

Taken together, what do these discoveries demonstrate?
the cumulative nature of science
the quantitative nature of science
the importance of thorough review of scientific papers
the importance of not publishing science until it is final

Answer 1

the cumulative nature of science

Each discovery built on the previous ones—Thomson found electrons, Rutherford found the nucleus, and Bohr refined the model of electron behavior—showing how scientific knowledge accumulates and improves over time.
