Q: What is chemistry?
A: Chemistry is the study of the properties and uses of elements. Chemistry is the study of the properties and uses of materials. Chemistry is the study of organic and inorganic substances. It once was believed that organic compounds were produced exclusively by living things, but scientists today can synthesize many organic materials from inorganic ones.

It once was believed that the chemical structure of elements was in the form of boxes or linear, but today these chemical structures are being questioned. Who proposed this chemical structure? How did they reach this type of chemical structure? What did they do to reach to this type of structure? Who verified the findings? It will be in the best interest of industry to focus on elements, their properties, and their uses. Thus, it will be in the best interest of industry to focus on materials, their properties, and their uses.
