Question

Which statement best explains why the atomic theory developed efficiently? Scientists ignored all previous knowledge about atoms. Scientists had used creativity in their investigations. Scientists had only used standard methods of investigation. Scientists repeated experiments to make sure the results were correct.

Answer 1

''Scientists repeated experiments to make sure the results were correct” is the one statement which best explains the development of atomic theory efficiently.

Answer: Option D

Explanation:

The atomic theory was first postulated by Dalton and then J.J.Thomson gave the first theoretical assumption on the model of atom. In order to prove the model of J.J.Thomson correct, Rutherford did the gold foil experiment.

But the outcome of the experiment gave birth to new model of atom termed as nuclear model of atom. Then Chadwick, Neil Bohr, Sommerfeld have conducted and repeated various experiments to conclude the present atomic theory.

Thus the repeated experiments done by the scientists to make sure the results were correct is the one which best explains the development of atomic theory efficiently.

Answer 2

Scientists had used creativity in their investigations is the statement best explains why the atomic theory developed efficiently.

Answer: Option B is the correct choice for the given question.

Explanation:

The basic purpose of experimentation and research is to get conclusions as a solid base for development of theories in science which can help humanity in many other factors.

By utilizing these theories many other experiments and development can be done.  Similarly while postulating the atomic theory scientist had to experiment and research many times and had to do things creatively to get to this important theory.
