Look up malleability in Wiktionary, the free dictionary.

Malleability is a mechanical property of matter, but is most commonly used in reference to metals and metalloids. A malleable metal is capable of being extended, shaped, or otherwise deformed without cracking. This property is important in metalworking, as materials that crack or break under pressure cannot be hammered or rolled. Malleable materials can be formed using stamping or form pressing, whereas brittle metals and plastics must be molded. Wikipedia does not have an article with this exact name. ...

Malleability occurs as a result of the specific type of bond found in metals (Main article: metallic bond). In metallic bonds, valence shell electrons are delocalized and shared between many atoms. This is often referred to as the "sea of electrons" and is responsible for many properties of metal. The delocalized electrons allow metal atoms to slide past one another without being subjected to strong repulsive forces that would cause other materials to shatter. Metallic bonds are found in metals like copper. ... The valence shell is the outermost shell of an atom, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms. ... For other uses, see Electron (disambiguation). ... In chemistry, delocalized electrons are electrons in a molecule that do not belong to a single atom or a covalent bond. ...

National Mall - Wikipedia, the free encyclopedia (841 words)
The National Mall refers specifically to the land stretching from the grounds of the Washington Monument to the United States Capitol directly to the east.
However, the term commonly includes the areas that are officially part of West Potomac Park and Constitution Gardens to the west, and often is taken to refer to the entire area between the Lincoln Memorial and the Capitol, with the Washington Monument providing a division slightly west of the center.
The National Mall is accessible via Washington Metro, with the Smithsonian station located on the south side of the mall, near the Washington Monument.
The Mall (London) - Wikipedia, the free encyclopedia (300 words)
The Mall (pronounced 'mal', not 'maul') in London is the road running from Buckingham Palace at its western end to Admiralty Arch and on to Trafalgar Square at its eastern end.
Running off The Mall at the eastern end is Horse Guards Parade, where the ceremony of the Trooping of the Colour occurs.
The Mall was created as a ceremonial route in the late nineteenth and early twentieth centuries, matching the creation of similar ceremonial routes in other cities, such as Washington DC, St.Petersburg, Paris, Berlin and Vienna.
