Chemical Bonding

This is when two or more atoms are close enough, you can produce an attractive force between the electrons of individual atoms and the nucleus of other atoms. if this force is large enough to hold together the atoms, is said to have formed a chemical bond.

Electronegativity and polarity of the bonds

Electronegativity is the ability of an atom of an element to attract shared electrons to whether its covalent bond with an atom of another element.

The account of the electronegativity and the polarity of the links

Is that the greater electronegativity deficiency will be more polar binding

Regladel octet

Stated in 1916 by Gilbert Newton Lewis, said that the tendency of electrons to atoms of acquiring such a configuration similar to that of a noble gas, located at the far right of the periodic table and are inert, so it is very difficult to react Aque although some elements are elements that meet the Lewis structure

Lewis structure

Also called Diarama point, model or representation of Lewis Lewis, is a graphical representation showing the bonds between atoms in a molecule and the lone pairs of electrons that may exist. The Lewis diagram can be used both to represent molecules formed by the union of its atoms through covalent and coordination complexes.

Metallic bond

In a metal, the bonding electrons are delocalized in a structure of atoms.

Hydrogen

It is the attractive force between an electronegative atom and a hydrogen atom covalently bonded to another electronegative atom.

Force van der Waals

It is the attractive or repulsive force between molecules or between parts of a single molecule other than those due to covalent bonds or electrostatic interaction of ions with one another or with neutral molecules.

London forces

They are the result of attraction between the positive and negative induced dipoles in adjacent molecules.

Types of link:

Ionic bond:

They consist of electrolytic attraction between electrically charged atoms of opposite sign.

Covalent bond:

Covalent bonds are the forces that hold each other non-metal atoms
