Question

which of the following is not a property of a metallic solid? amorphous high boiling point high melting point held together by a sea of delocalized electrons

Explanation:

Metallic solids have a crystalline structure (ordered arrangement of atoms), so they are not amorphous (amorphous means lacking a definite crystal structure, like glass). High boiling and melting points are typical of metallic solids due to strong metallic bonding, and they are held together by a sea of delocalized electrons.

Answer:

A. amorphous
