VIDEO: 'DRAWING ATOMS, HATFIELD STYLE'

In this VIDEOMr. Hatfield demonstrates his flat, two-dimensional, cartoony and unrealistic way to draw atoms. But that's not a bad thing.

Atoms don't 'look like' anything in the real world, so every attempt to draw them is going to be unrealistic in some sense: they're smaller than visibile light, after all!

But, Mr. Hatfield's way of drawing atoms does allow you to distinguish at a glance between the internal structure of a standard neutral atom, an ion or an isotope---and that can make all the difference in understanding the way that different substances (elements and compounds) actually behave.
