Question

Observation and experimentation have led scientists to accept a theory about the atom. This theory is called the Atomic Theory. Scientific evidence collected and observed by scientists over time suggests that the atom has a nucleus, containing protons and neutrons, and electrons that travel as waves around the nucleus. What makes this a scientific theory?

Answer 1

Answer;

It is the best explanation that scientists can offer, based on many scientific investigations

Explanations.

• Scientific Theory is an explanation supported by a large amount of evidence; best explanation based upon what we know. It is a theory that has been tested and proved. It needs to be proven and tested multiple times to be even stronger.
• Evidence refers to the results collected when a theory or hypothesis is tested. Scientific evidence serves to either support or counter a scientific theory or hypothesis.
• Scientific theory explains observations or events  based on knowledge gained from many investigations and observations.

Answer 2

It is a scientific theory because it is built on investigations by many scientists in order to provide a strong and testable explanation. A scientific theory is an in-depth explanation, whereas a scientific law is statement about an observed phenomenon or a unifying concept.
