Which aspect of metallic bonding best accounts for the characteristic malleability of metals g?

Malleability is the property of metals in which they can be drawn into thin sheets. Metallic bonding accounts that there is no specific bonding and the electrons are free and are moving.

Explanation:

Electron sea model:-

It assumes that the electron of the metal atoms tends to flow between the nuclei of the metal easily.  

It is model which shows the metallic bonding in which the cations of the metal are at the fixed places and the negatively charged electrons move freely within them.

Thus, malleability is the property of metals in which they can be drawn into thin sheets. Metallic bonding accounts that there is no specific bonding and the electrons are free and are moving. Thus, it is able to draw them into sheets.
