There is also a specially designed lesson meant to help complement this quiz called The Octet Rule and Lewis Structures of Atoms and you can use this lesson to learn more about this key rule in chemistry. The lesson covers these topics: ...
lewis structuresThe octet rule proposed by Lewis states that the valence shell of an atom in a molecule always has eight electrons in its valence shell when each pair of shared electrons is counted as contributing fully and equally to the valence shell of both bonded atoms irrespective of the ...
The Lewis structure is named after Gilbert N. Lewis, who first introduced the concept in his article, “The Atom and the Molecule” in 1916. Lewis structures only represent the valence electrons, which are identified as dots around the atom, each dot representing one valence electron. Most of...
While Lewis structures have some value, the reader is advisedvalence bond theoryandmolecular orbital theorydo a better job describing the behavior of valence shell electrons. Sources Lever, A. B. P. (1972). "Lewis Structures and the Octet Rule. An automatic procedure for writing canonical forms...
刘易斯符号(Lewis Symbols) 元素的刘易斯符号由元素的化学符号加上每个价电子的点组成。例如,硫的电子构型为[Ne]3s23p4,因此有六个价电子。它的刘易斯符号是 这些点位于符号的四个边——顶部、底部、左侧和右侧——每个边最多可容纳两个电子。所有四个边都是等价的,这意味着放置两个电子,放置一个电子或者不放电...

This misinterpretation of the Lewis octet rule has led to much controversial discussion in connection with the concept of hypervalent molecules which have more than eight electrons in the valence shell of the central atom in their Lewis structures. Whereas hypervalent molecules clearly do not obey ...
