chapter 10 section 3 notes

Question 1

six properties of solids and expalin each in terms of the kinetic molecular theory of solids

Answer 1

particles of a solid are closely packed (definite shape)
dipole to dipole attractions
london dispersion forces and hydrogen boding exert stronger effects in solids than in corresponding liquid or gases.
particles vibrate in a fixed position
definite volume
definite melting points because kinetic energy is needed to overcome attractive forces
high desnity
incompressible
low rate of diffusion
lower kinetic energy

Question 2

four common examples of amorphous solids

Answer 2

glasses, plastics, synthetic fibers, rubber

Question 3

describe ionic crystals

Answer 3

ionic cystals- ions arranged in regular pattern
monoatomic or polyatomic. strongin bonding forces
high melting points
good insulators

Question 4

describe covalent network crystals

Answer 4

each atom is covalently bonded to its nearest neighboring atoms. 3 dimensional covalent network. single atoms covalently bonded in a pattern.

Question 5

describe metallic crystals

Answer 5

consists of metals cations surrounded by a sea of delocalized valence electrons

Question 6

describe covalent molecular crystals

Answer 6

consists of covalently bonded molecules held together by intermolecular forces.

Question 7

describe polar molecular cyrstals bond

Answer 7

dispersion forces
