3.1 Atom
CK-12 Physical Science For Middle School > Atom
Written by:Jean Brainard, Ph.D.
What could this hilly blue surface possibly be?
Do you have any idea? The answer is a single atom of the element cobalt. The picture was created using a scanning tunneling microscope. No other microscope can make images of things as tiny as atoms. How small are atoms? You will find out in this lesson.
Discovering the Atom
Atoms are very tiny, so tiny that they could not be seen before scanning tunneling microscopes were invented in 1981. However, the atom and its parts were discovered long before the tunneling microscope was invented. How did scientists discover the atom if they couldn’t see it? They made models. A scientific model is a tool constructed by the scientist based on all the known experimental evidence about a particular thing, such as an atom. The first model of the atom goes back to ancient Greece. As time went by and more experiments are performed, models evolve and change to account for new understanding. Explore the timeline below to see how the model of the atom was initially developed and how it has changed over time into what we now have come to accept as the modern model of the atom.
