Answer:

Step-by-step explanation:

E. The atoms in amorphous silica do not pack as efficiently in three dimensions as compared to the atoms in quartz.

Step-by-step explanation:

Quartz is a crystalline structure with a lattice which is very compact and produces flat faces that align with one another causing high density.

Silica has covalent bonding and forms a network structure. Silica, SiO2 is an amorphous solid and does not posses the same lattice or crystalline structure as Quartz, making it less dense.
