Question
What is Lewis structure of an atom and anion?
Solution
Lewis symbols or electron dot symbols (Lewis structure): According to the Lewis concept, the symbol of an element stands for the nucleus as well as electrons in the inner enthalpy shells (which are not involved in bond formation). The valence electrons are represented by dots near the symbol of the element. These symbols are known as Lewis symbols or electron dot symbols. In the case of ions, the ionic charge is also shown along with the symbol. For example, the Lewis structure of H, H+, Mg, Mg2+, F and F– ions are shown as follows:
