The electronic configuration of an atom determines its chemical properties from "summary" of Chemistry Simplified NCERT Class 11 by Sanjay Sharma
The electronic configuration of an atom is a crucial factor that determines its chemical properties. Electrons in an atom are arranged in energy levels or shells around the nucleus. These energy levels are further divided into sublevels, which can hold a specific number of electrons. The distribution of electrons in these energy levels and sublevels plays a significant role in how an atom interacts with other atoms to form compounds. The number of electrons in the outermost energy level of an atom is particularly important in determining its reactivity. Atoms tend to gain, lose, or share electrons in order to achieve a stable electronic configuration. This is because atoms are most stable when their outermost energy level is either completely filled with electrons or contains eight electrons, known as the octet rule. This stability is achieved by forming chemical bonds with other atoms. Atoms that have a nearly full or nearly empty outerm...
