WebAlmost 100 years ago, the American chemist Gilbert Lewis proposed that chemical bonds arise from the sharing of pairs of electrons between atoms. In a 1916 paper, 1 he portrayed atoms as cubes with electrons at their corners, and argued that they accumulate an electron at every corner by sharing edges with other atoms. WebLewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Lewis structures show each atom and its position in the structure of the molecule using its chemical symbol.
