Covalent Network Solids
These are a type of solid that have molecules held by intramolecular covalent bonds into continuous 2D or 3D arrays.
SiO₂, silica, is a staple example of a network covalent solid.
However, there are reasons as to why the other options are incorrect:
- K is a type of metallic solid, where metal ions of the same kind are bonded through a shared attraction to the valence sea of electrons.
- I₂ contains covalent bonds, but it is a molecular solid made of molecules held together by weaker intermolecular forces.
- CaCl₂ is a type of ionic crystal, composed of ions in a crystal lattice structure.
