A friend in your chemistry class is struggling to understand why crystalline solids are grouped into four main types: network, molecular, ionic, and metallic. Which explanation below will BEST help him begin to understand why chemists might have these groups?
Crystalline solids all share a lattice structure, but have different densities. Chemists use the groups to organize the solids by density.
Crystalline solids all share a lattice structure and the same types of bonds, but are composed of different elements. These elements affect the way the solid conducts heat and electricity.
Crystalline solids all share a lattice structure, but behave differently under similar conditions.
Crystalline solids all share a lattice structure, but the bonds that hold them together at the atomic level differ. The elements that make up the solids also differ. These differences affect how a solid conducts heat and electricity.

Which of the following is a characteristic property of crystalline solids?
They have a definite and regular arrangement of atoms.
They do not have a sharp melting point.
They are isotropic in nature.
They do not conduct electricity.
What type of crystalline solid is diamond?
Ionic
Molecular
Metallic
Covalent Network
Which experiment can be used to determine the crystal structure of a solid?
X-ray diffraction
Titration
Electrolysis
Centrifugation
Why do ionic crystalline solids have high melting points?
Due to strong covalent bonds
Due to strong electrostatic forces between ions
Due to weak van der Waals forces
Due to metallic bonding
Which of the following is an example of a molecular crystalline solid?
Sodium chloride (NaCl)
Ice (H2O)
Iron (Fe)
Diamond (C)
