Explain that a scientific paradigm is a theoretical model of how nature works, using chemistry examples such as phlogiston, historical atomic models, or the periodic table and periodicity.
Explain with examples, that a scientific paradigm is a theoretical model of how nature works( some examples include: . The belief that materials that burn do so because a material called "phlogiston" was the paradigm in chemistry in the 18th century, b. Historical models of the atom are paradigms, such as plum-pudding and the Rutherford model of atom, c. The periodic table of elements, and belief in the " periodicity" of atoms based on the arrangements of their electrons is a paradigm.
