It was based on the thoughts of an early philosopher.
Atoms are the topic of interest for many scientists.
Atoms of the same element may differ from one another by having differing numbers of Neutrons in their centres.
evaluate the impact of research on the way scientists thought about atoms
Atoms could be identified by various technique. Single crystal X-ray diffraction is the most important in that.
The resulting atoms are isotopes of nitrogen, most probably N-15.
21 different kinds of atoms
They view atoms through an electron microscope.

Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.
So as to explain the properties of atoms.
how does the modern view differ from this ancient view
No. Atoms differ in the number of protons, neutrons, and electrons.
Atoms of the same element may differ from one another by having differing numbers of Neutrons in their centres.
