Chemicals are produced through a combination of reactive elements, and can be found in solid, liquid, or gaseous states. The term "chemical" refers to a vast number of substances and processes that cannot be fully addressed in a single comprehensive manner, but by focusing on those in the pharmaceutical and industrial fields it is possible to derive some general information. In natural or artificial forms, these specific chemicals play a crucial role in the production of industrial components and medicines. Although chemicals are common in day-to-day life, proper care must also be taken when handling them, particularly those with the potential for harmful or volatile reactions.
Chemicals are integral to modern society, whether in medicine, industrial manufacturing, or the production of foods, glues, and plastic. Chemical substances can be broadly categorized as metal, non-metal, compound, element, and covalent types. Manufacturers have used the chemicals in these categories to not only create products, but also a wide range of specialized professions, such as engineers and chemists.
