Why metals are malleable ductile and durable?

Answer 1

Metals have good conductivity, malleability, ductility, and luster because of the properties of their electrons. The electrons are not tightly bound to any one atom, and thus form a sea of loosely bound electrons around the metal atom cores. This phenomenon occurs because there is overlap between the valence band and the conduction band in metals.

Answer 2

Metals are malleable because they are able to be hammered or pressed permanently out of shape without breaking or cracking. Metals are malleable because they can be fashioned into a new form of a something. They are durable because they are very strong.

Answer 3

malleability refers to metals which can be hammered into different shapes. ductility refers to metals which can be drawn into wires. Not all metals are malleable or ductile. Cast iron, for example, is quite hard but brittle. But metals that are malleable or ductile are so because of the way in which atoms are arranged. In a metal the atoms lie close together and, while they strongly attract one another, may be able to "flow" past each other whilst maintaining their proximity, and the metal's shape can be changed.

In metals, the valence (outermost) electrons of the metal atoms are in fact not bound to their parent atoms, but in fact roam relatively freely between atoms, in a "sea" of sorts (in the simplest picture). This allows them to travel around, carrying electrical current with minimal resistance. This sea of electrons model also helps to explain malleability and ductility. Sine the bonds between metal atoms are not forced into specific orientations(such as in organic molecules) the metal atoms can flow past each other without breaking and remain bound to each other. this confers malleability and ductility.
