Lewis structures cannot accurately represent the three-dimensional shape of molecules or the dynamic nature of electron distribution. They also may not fully convey resonance or the presence of delocalized electrons in certain compounds. Additionally, while they illustrate bonding and lone pairs, they do not provide information about the relative sizes of atoms or the strengths of bonds.
Resonance structures refer to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure. The Lewis dot structures show valence electrons.
There are three equivalent Lewis structures for CO32.
Electron dot structures are sometimes called Lewis dots or Lewis structures because they were introduced by American chemist Gilbert N. Lewis in the early 20th century. Lewis used dots, or small circles, to represent valence electrons around atoms in a chemical structure, which is why these diagrams are often referred to as Lewis dots or Lewis structures.
Two equivalent Lewis structures are necessary to describe SF4. These structures differ in the arrangement of the lone pair on sulfur, resulting in resonance structures.
The Lewis structures were introduced by the American chemist Gilbert N. Lewis in 1916. Lewis proposed the concept to represent the bonding between atoms in a molecule using simple symbols and dots to denote valence electrons.
Two equivalent Lewis structures are necessary to describe the bonding in BrO4 due to the presence of multiple resonance structures.
Lewis structures show the arrangement of valence electrons in a molecule, indicating bonding and nonbonding pairs. Kekule structures specifically refer to resonance structures used to depict the delocalization of electrons in aromatic compounds like benzene. Lewis structures are used for any molecule, while Kekule structures are specific to aromatic compounds.

Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.
Two equivalent Lewis structures are necessary to describe the bonding in SeBr2O. This is because the central selenium atom can form two different resonance structures by moving a lone pair from the oxygen atom to form a double bond with selenium.
