How has scientific experimentation affected the model of an atom? a. the atomic model has become more accurate because of this experimentation. b. the atomic model has become a less accurate representation of the actual atom. c. we understand less about the atom due to these experiments. d. we are less able to design an accurate model as a result of these experiments.

Option (a) is the correct answer.

Explanation:

Before experimentation we were not aware of the sub-atomic particles present in an atom. But after the experimentation, we came to know that an atom consists of protons, neutrons and electrons.

After that we came to know that protons and neutrons reside inside the nucleus and electrons revolve around the nucleus of the atom.

Hence, we can conclude that scientific experimentation affected the model of an atom such that the atomic model has become more accurate because of this experimentation.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
