chemistry of solids

Question 1

network solids

Question 4

Answer 4

metallic solids are held together by __COVALENT_BONDS_BETWEEN_NUCLEI______ in a lattice structure

Question 5

metallic solids are surrounded by a _______

Answer 5

metallic solids are surrounded by a __SEA OF VALENCE ELECTRONS_____

Question 6

metallic solids are ______ of electricity and ________

Answer 6

metallic solids are ___CONDUCTORS_____ of electricity and __HEAT______

Question 7

molecular solids are held together by ___________ in a lattice structure

Answer 7

molecular solids are held together by __INTERMOLECULAR_INTERACTIONS_BETWEEN_MOLECULES______ in a lattice structure

Question 8

______ solids have the weakest attractive forces

Answer 8

molecular solids

Question 9

how to remember

Answer 9

ionic solids = ions are individual unit
molecular solids = molecules are the individual unit

if ions are the individual unit -> ionic bonds
if molecules are the individual unit -> intermolecular bonds = (IMF)

metallic solids = metals
metals are good conductors
good conductors have valence electrons

network solids
think of it as ONE big molecule
in ONE molecule the only bonds we find are COVALENT –> network solids intermolecular force = covalent bond the intramolecular force is covalent bonds
figure out a way to remember its covalently bonded atoms

Question 10

molecular solids are often this phase at room temperate

Answer 10

liquids or gases
