Electron dot structures, also known as Lewis dot structures, are diagrams that represent the valence electrons of atoms within a molecule. These structures help predict the arrangement of atoms, the number of bonds, and the presence of lone pairs in a molecule, providing insight into its chemical properties and reactivity.

Valence electrons are the outermost electrons of an atom and play a crucial role in determining its chemical properties and reactivity. They are involved in forming chemical bonds, such as covalent and ionic bonds, and dictate how atoms interact with each other in molecules and compounds.

Chemical properties describe the potential of a substance to undergo chemical changes or reactions due to its composition. These properties are intrinsic to the substance and determine its behavior in chemical processes, influencing how it interacts with other substances.

Chemical Properties

Reactivity refers to the tendency of a substance to undergo chemical reactions, either by itself or with other materials, which is influenced by factors such as electron configuration, temperature, and pressure. Understanding reactivity is crucial in predicting the behavior of substances in various environments and in designing chemical processes and materials.
