Formal Charge
Formal charge is a concept within chemistry that aids in understanding the distribution of electrons in a molecule or ion. It provides valuable insights into the stability and reactivity of chemical species. In essence, formal charge allows chemists to assign hypothetical charges to atoms within a molecule, providing a means to evaluate the relative contribution of each atom to the overall charge of the species. Understanding formal charge is fundamental to predicting molecular structure, chemical bonding, and reaction mechanisms in both organic and inorganic chemistry.
