Types of solids are:
• Ionic solid: composed of a metal and a nonmetal as ions.
• Molecular solid: composed of covalent bonds.
• Metallic solid: composed of metal and another metal or just a metal by itself.
• Covalent solid: also called a network solid where atoms are bonded by covalent bonds in a single continuous network.
a. Elemental silicon, Si(s)
• silicon atoms are connected are bonded by covalent bonds in a single continuous network
b. Diamond, C(s)
• carbon atoms are connected are bonded by covalent bonds in a single continuous network
c. Buckminster fullerene, C60(s)
Which of the following is NOT a network solid and WHY?
