Lewis theory

Lewis theory, developed by Gilbert N. Lewis, explains how atoms bond to form molecules by sharing electrons. Central to this theory is the idea of the "octet rule," which states that atoms tend to bond in such a way that they each have eight electrons in their outer shell, achieving stability. Lewis structures are visual diagrams that represent these electron arrangements, showing how atoms are bonded and where lone pairs of electrons reside. This theory helps clarify the formation of covalent bonds, which are crucial for understanding chemical reactions and the behavior of substances in chemistry.
