Chemical bond - Wikipedia

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. Web25 de jan. de 2024 · Definition of Chemical Bond The phenomenon of the union of two or more atoms involving the redistribution of electrons so that each atom involved in bonding acquires a stable electronic configuration to gain stability is known as chemical bonding.

Lewis’s 1916 paper entitled ‘‘The Atom and the Mole-cule.’’1 This remarkable and revolutionary paper laid the founda-tion for much of our present day understanding of two funda-mental concepts of chemistry: The chemical bond and molecular structure.

WebChemical bonds are forces that hold the atoms together in a molecule. They are a result of strong intramolecular interactions among the atoms of a molecule. The valence (outermost) electrons of the atoms participate in chemical bonds. When two atoms approach each other, these outer electrons start to interact.

WebIn 1916, G. N. Lewis proposed that a chemical bond forms by the interaction of two shared bonding electrons, with the representation of molecules as Lewis structures.
