Even to this day, knowledge about atoms is helping researchers in all fields of experimental and theoretical research. In the 1970s it helped in the development of the understanding of stockholder partitioning of atoms in molecules which is a major theoretical tool used in entropy concept (Nalewajski and Patt, 2000) Conclusion Dalton’s concept about the atomic world had indeed opened up a vast expanse of information about the natural world.

Ceramic structures appear metallic, and that is how they led to the discovery of metallic materials (David, 2006).
