A tool designed to visually represent the valence electrons of atoms within a molecule. It assists in understanding chemical bonding and molecular structure by depicting electron arrangements as dots surrounding the atomic symbol. These diagrams illustrate how atoms share electrons to achieve a stable electron configuration. For instance, it displays the distribution of electrons in a water molecule, clearly showing the shared electrons between oxygen and hydrogen atoms.
The creation of these visual aids allows for quicker identification of bonding patterns and potential molecular geometries. This facilitation speeds up the process of predicting molecular properties, such as polarity and reactivity. Historically, developing these representations manually was time-consuming, but computational tools now automate the process, significantly improving efficiency and accuracy in chemical analysis.
