Step-by-step explanation

Step 1.

 is a metallic solid.

is a non-bonding atomic solid.

Metallic solids have composite units as metal ions in a sea of electrons. Hence the force of attraction between the ions and the sea of electrons is a strong metallic bond. 

Non-bonding atomic solids are solids whose composite units are individual atoms. The lattice sites in a crystalline atomic solid are therefore occupied by non-bonded atoms They are held together by the kinds of intermolecular forces—dispersion forces,dipole-dipole forces, etc.
 
is a non-bonding atomic solid with weak dispersion forces as the intermolecular force.
