Explanation of Aufbau’s Principle

Field of Chemistry is all about of the study of composition of existing substances and synthesis of newer substances. Aufbau’s principle predicts Valency and electron configuration that are responsible factors for formation of newer substances. In this article, I’m going to provide a detailed explanation of Aufbau’s principle.  Aufbau’s principle highlights the proper selection of
