A Lewis structure can be drawn for any covalentlybonded molecule, as well as coordination compounds. The Lewis Structure was named after G.N. Lewis, who introduced it in his 1916 article The Molecule and the Atom.  \nLewis structures show each atom in the structure of the molecule using its chemical symbol. Lines are drawn between atoms that are bonded to one another (rarely, pairs of dots are used instead of lines) . Excess electrons that form lone pairs are represented as pair of dots, and are placed next to the atoms on which they reside.  \nThus, the lewis package enables the user to typeset rudimentary Lewis Structures within LATEX documents.  \nUsage  \nThere is but one command in the lewis package: nlewisfX gf . gf . gf . gf . gf . gf . gf . gf . g  \nSuch that X is the desired chemical symbol around which the electron dots will be placed. Each f . g represents the symbol that will be placed in the electron dot position, beginning with the lower left hand position and proceeding clockwise around the symbol, X. Thus, nlewisfX gf1gf2gf3gf4gf5gf6gf7gf8g would produce:  \n3 4  \n21 X 56  \n8 7  \nBecause the most common usage of the lewis structures is to place dots within positions 1-8, the period f . g is an ideal choice:  \n: :  \n:: X ::  \n: :  \nThere is one caveat, however, which is that the in􀀌nite con􀀌gurability of lewis structure diagrams is very di􀀎cult to program and so arrays and alignment tweaks such as nhspace may ultimately be needed to achieve the desired results. What follows are several textbook examples of Lewis Structures, as well as the code needed to produce them.  \nExamples  \n1) The bonding of two 􀀍uorine atoms with a xenon atom to produce xenon  \n: : : : : :  \ndi􀀍uoride (XeF2 ) may be represented as :::F: { X: :e { F: :::  \nThe responsible code:  \n\\lewis{F}{.}{.}{.}{.}{}{}{.}  \n{.}\\hspace{-0.5em}--\\hspace{-0.75em}\\lewis{Xe}{}{}{.}{.}{}{}{.}{.}\\hspace{-0.5em}--\\hspace{-0.75em}\\lewis{F}{}{}{.}{.}{.}{.}{.}{.}  \n: :  \n2) Carbon dioxide (CO2 ) would look like :: O: = C = O: ::  \nThe responsible code:  \n\\lewis{O}{.}{.}{.}{}{}{}{}  \n{.}\\hspace{-0.5em}=\\,C\\,=\\hspace{-0.75em}\\lewis{O}{}{}{}{.}{.}{.}{.}{}  \nH H  \n3) Water (H2 O) might look like n =  \n: O :  \n: :  \nThe responsible code:  \n\\lewis{O}{.}{}{  \n\\lewis{H}{}{}{}{}{}{}{{\\backslash}}{}}{\\lewis{H}{}{}{}{}{}{}{}{{/}} }{}{.}{.}{.}  \nAs you can see from the third example, more complex structures are both harder to code and less elegant. Nonetheless, the building blocks for individual electron dot diagrams are present and lend themselves naturally to more complex structures. Hopefully future versions will reduce the number of alignment issues and provide additional commands for higher energy level elements.","cbCaisGFYNpxCGIZ","https://ap.wps.com/l/cbCaisGFYNpxCGIZ","pdf",47067,"English","# Introduction\n# Usage\n# Examples\n## XeF2\n## CO2\n## H2O","[{\"question\":\"What is a Lewis structure and what information does it display?\",\"answer\":\"A Lewis structure, also called an electron-dot structure, shows bonding between atoms and lone pairs of electrons in a molecule.
