Which statement best explains why the atomic theory developed efficiently?

• A. Advancements in experimental techniques allowed scientists to gather more accurate data about atoms.
• B. All elements were discovered before the atomic theory was proposed.
• C. The atomic theory was accepted without any experimental evidence.
• D. Atoms were directly observed using microscopes in the early 1800s.

Answer: (A)

Verified step by step guidance

1. Understand that the atomic theory is a scientific model developed to explain the nature and behavior of atoms based on experimental evidence.
2. Recognize that scientific theories develop efficiently when there are advancements in experimental techniques, allowing scientists to collect more precise and reliable data.
3. Evaluate the given statements by considering historical context: early atomic theory was based on indirect evidence rather than direct observation, as atoms are too small to be seen with early microscopes.
4. Note that not all elements were discovered before the atomic theory; new elements continued to be found after the theory was proposed, so this is not the reason for efficient development.
5. Conclude that the best explanation is that improvements in experimental methods enabled scientists to gather accurate data, which supported and refined the atomic theory over time.
