They view atoms through an electron microscope.
An electron microscope.

The good kind! :D
Well the atoms are never going to change but, as you can see the more scientists study the atom we have the ability to add to our technology.
"View" may not be exactly the right word. A Scanning Tunneling Microscope can be used to gather data that a computer can turn into an image, but they're not really "seeing" the individual atoms directly.
21 different kinds of atoms
Scientists use models to study atoms because atoms are too small to be seen with the naked eye. Models provide a visual representation of atoms that helps scientists understand their structure and behavior. By using models, scientists can make predictions and test hypotheses about atomic interactions.
how does the modern view differ from this ancient view

So as to explain the properties of atoms.
The alchemists were unaware that atoms even existed.
Scientists don't believe atoms exist- they know atoms exist. No matter what type of field they study, the 'theory' of the atom explains many things about matter and chemistry and what make things happend in the physical world.
