Chemistry key words and definitions

An electrically neutral group of two or more atoms held together by chemical bonds is the most basic definition of molecule. In that sense, no, by nature, a molecule can not be formed from a single atom. Adjective

The term chemical change is used throughout the many specialized fields of chemistry, including organic chemistry, inorganic chemistry, biochemistry, and electrical chemistry. Not surprisingly, chemical changes are discussed and analyzed by scientists and science teachers and written about in science textbooks and articles, but does the subject ever come up in just ordinary, everyday life? Absolutely! Check it out: Most of the topics have been clearly explained, there are some that might need to be explained better. For example in bond polarity table, 0.4 difference between electronegativities might be considered for either “slightly polar covalent” or “definitely polar covalent” bond. There are also questions about expanded octet Lewis structures, (question 9 in 9.7 End-of-Chapter Material), that can’t be answered by the information provided in the text book

Chemistry terms and definitions

Absorptivity – Adsorptivity is the absorption cross section or extinction coefficient. Absorptivity varies with wavelength and is defined as the absorbance of a solution per unit path length and concentration:a = A/(bc)where a is absorptivity, A is absorbance, b is path length, and c is the concentration. Glossary of Definitions and Commonly Used Terms Azimuthal quantum number – Azimuthal quantum number is another name for angular momentum quantum number. See definition above.
