What does it mean if a solid is malleable?

Malleability, the ability of a material to be hammered out into a sheet (from the Latin, $"malleus, hammer"$, is a fundamental property of metals. Solid non-metals, e.g. diamond, sulfur, iodine,...

$"Metallic bonding"$ results from the close packing of metal atoms, such that the atoms contribute a few of their to the overall lattice. These are delocalized, and not associated with...

Apparently none. Malleability is a property of metals, a result of the between atoms of the metal. I suspect it is closely related to ductility, the ability of a substance...

is an electrostatic bond between metal cations and delocalised electrons. Since the metal atoms are in layers on top of each other, these layers can move over another and...

In a metallic bond, each metal atom is conceived to donate one or two or more to the bulk lattice. The result is commonly described as $"metallic bonding"$, $"positive ions...

$CO_2(s)$ is molecular, with the individual molecules held together by (weak) dispersion forces. Sodium exhibits ; i.e. positive ions in an electron sea, which gives rise to demonstrable malleability and...

$"Sodium"$ exhibits ........ $"Sodium sulfide"$ is an ionic solid, i.e. $Na_2S$ And $"solid carbon dioxide"$, i.e. $"dry ice"$, is a molecular solid.

........and we further know that the blue solid was a compound and NOT an element. The blue substance evolved (i) a gas, and (ii) a new white substance. Given the...

In a solid state, all the particles are closely compact, however they do vibrate, but they do keep a fixed shape. They do not have enough energy to break the...

The phase change from a condensed to a gaseous phase represents a clear, and readily appreciated increase in entropy. Likewise, the dissolution of a solid in a (sugar in water)...
