Why are atoms sometimes shown using models like the one in this picture?

Answer 1

There are different representations because different chemist discovered different things at different times. So all the different diagrams show what people at different periods in history thought and, as we find out more we are able to learn which idea is the most accurate.

Answer 2

Vastly different models of the same thing are often used due to the Heisenberg Uncertainty Principle, the speed and location of a mass-less object (electron) can not be know at the same time. Thus, electrons can not be depicted. And, there is no known color of atoms, so differences between protons and neutrons can not be depicted. Pictures of atoms have not been taken, so not much is known about how they look in real life. Therefore, models must be made. Different models were made by different people, and although there is a generally accepted form, this is all speculation.

Answer 3

Do you mean the way it's shaped? The properties they have put them in special places.

If you mean different colors and lines, please specify.

Answer 4

An atom is representative for a chemical element.

Answer 5

elements
