INTRODUCTION
In this work ,primarily attempts to explain the formation of molecules andelectrons that occur in them ,the way they are held together and exchange of electrons. of this type are called Lewis diagrams or Lewis structures. also their way of naming.

Covalent bonds and Lewisstructures
1. Do a conceptual map based in the reading have on count the connectors and make that everything is clear

Covalent bonds and Lewis structures

Refers to the explanation given in thechemical bonding by a first stay Kossel that can not be applied to homonuclear molecules. Then comes thereby applying the theory of LewisThe lack of reactivity of the noble gases
Whit This:

Kossel and Lewis both were very impressed to see:

And noted that the vast majority of the molecules havean even number of electrons

Same with them are
DIAGRAMS

They are called lewis diagrams, a bond between two atoms could be called a commonly shared linkor covalent enlase.in the preparation of these the atomic nucleus nucleus is represented by the symbol of the element and the valence electrons-

The complete symbol for each element can be calledlewis symbol Also the number of unpaired electrons equals the number of bonds that the atom can form ie the number of valence
The first four arranged singly around the symbol for the nucleus, withadditional electrons are used to form pairs

By

Lewis called the apparent tendency of atoms to acquire an array of noble gas electron

Electron arrangement achieves a noble gas even whenforming the maximum number of links. A covalent bond (a shared pair of electrons) is generally designated by a connecting line rather than by a pair of points
The formation of ions or by sharing pairs of...
