a few samples of the atom symbol in my paintings |
If you'd like to read a little bit about the Atomic Theory, i added an excerpt from an article on How Atoms Work...

Article: How Atoms Work
written by: Craig Freudenrich, Ph.D.
*The idea of the atom was first devised by Democritus in 530 B.C. In 1808, an English school teacher and scientist named John Dalton proposed the modern atomic theory. Modern atomic theory simply states the following: *
- Every element is made of atoms
- All atoms of any element are the same
- Atoms of different elements are different (size, properties)
- Atoms of different elements can combine to form compounds
- In chemical reactions, atoms are not made, destroyed, or changed
- In any compound, the numbers and kinds of atoms remain the same
Can We See Atoms?
Atoms are so small that we cannot see them with our eyes (i.e., microscopic). To give you a feel for some sizes, these are approximate diameters of various atoms and particles: - atom = 1 x 10-10 meters
- nucleus = 1 x 10-15 to 1 x 10 -14 meters
- neutron or proton = 1 x 10-15 meters
- electron - not known exactly, but thought to be on the order of 1 x 10-18 meters
