What are the four types of solids?
Ionic, molecular, network covalent, metallic
Name four examples of ionic solids.
NaCl, MgBr2, MgSO4, NH4CL
What are the structural particles of ionic solids?
cations and anions
Ionic: Force within the particle
None
Ionic: Forces between the particles
ionic bond
Ionic: Four properties
-nonvolatile
-high melting pts(600-2000 *C)
-solids do not conduct electricity; liquids and solutions do
-many are soluble in water ("solubility rules"); insoluble in organic solvents
Molecular: 4 examples
I2, H2O, C12H22O11
Molecular: structural particles
molecules (polar or nonpolar molecules)
Molecular: Forces within particles
covalent bonds
Molecular: Forces between particles
intermolecular forces (Hydrogen bonds, dipole forces, dispersion forces)
Molecular: 4 properties
-most are nonconductors as solids or in water (some polar molecules do conduct in water)
-most are insoluble in water (some polar molecules are soluble in water); soluble in organic solvents
-volatile (evaporate easily)
-low melting & boiling pts (many ar
Network Covalent: 5 examples
C, Si, SiO2, Ge, SiC
Network Covalent: Structural Particles
Atoms
Network Covalent: Forces within Particles
None
Network Covalent: Forces between particles
Covalent Bonds
Network Covalent: Three Properties
-Very high melting points(>100*C)
-Insoluble in all common solvents
-Poor electrical conductors (except for graphite)
Metallic: 4 Examples
Fe, Na, Ca, Ag
Metallic: Particles
Cations Mobile Electrons
Metallic: Forces Within Particles
None
Metallic: Forces Between Particles
Metallic Bonds
Metallic: Five Properties
-high electrical & thermal conductivity
-ductile, malleable
-luster
-insol. in water and other common solvents
-wide range in melting pts
