Definition Of A Metallic Bond
Definition Of A Metallic Bond. Metallic bonding is a force that binds atoms in a metallic substance together. This bond is formed from the attraction between mobile electrons and fixed, positively charged metallic atoms.
This bond is neither covalent nor ionic. ‘metallic bond’ is a term used to describe the collective sharing of a sea of valence electrons between several positively charged metal ions. Instead, many electrons (roughly one for each atom) are more or less free to move throughout the metal, so that each electron can interact with many of the fixed atoms.
The Atoms That The Electrons Leave Behind Become Positive Ions, And Their Interaction With Valence Electrons Produces The Cohesive Or Binding Force That Binds The Metallic Crystal Together.
The type of bond occurring in metals, in which the valence electrons are not localized as in covalent bonds but are capable of interacting with an indefinite number of the metal nuclei, which are arranged in a lattice formation. A metallic bond is a type of chemical bond similar to a covalent bond. Metallic bond the chemical bonding that holds the atoms of a metal together.

In A Sample Of Metal, The Valence Electrons Detach From The Atoms And Are Free To Move Throughout The Metal.
Metallic bonding accounts for many physical properties of metals, such as strength, ductility, thermal and electrical. Metallic bonds are formed from the attraction between mobile electrons and fixed, positively charged metallic atoms. The metallic bond is a unique type of chemical bond found in metal elements.
Understood As The Sharing Of Free Electrons Among A Lattice Of Positively Charged Ions, Metallic Bonding Is Sometimes Compared With That Of Molten Salts;
The chemical bond typical of the metallic state and characterized by mobile valence electrons that hold the atoms together usually in crystal lattices and are responsible for the good electrical and heat conductivity of metals. Instead, many electrons (roughly one for each atom) are more or less free to move throughout the metal, so that each electron can interact with many of the fixed atoms. Metallic bonding constitutes the electrostatic attractive forces between the delocalized electrons, called conduction electrons, gathered in an electron cloud and the positively charged metal ions.
| Meaning, Pronunciation, Translations And Examples
Factors affecting the strength of metallic bonding include the charge of the ion and the size of the ion. There are several theories to explain this type of bonding, among them the electron sea model is most popular. Delocalised electrons are free to move throughout the whole structure.
