|
electrons
|
subatomic particles outside the nucleus, equal in number to protons in neutrally charged atoms.
|
|
|
types of elements involved
|
IB metals and nonmetals
CB nonmetals |
|
|
basic unit of compound
|
IB formula unit _____
CB molecules |
|
|
force of attraction between the basic units
|
IB electrostatic force (depends on size and charge)
|
|
|
force of attraction
|
IB electrostatic force (depends on size and charge)
CB intermolecular forces, bond length (dpends on polarity), dipole-dipole forces |
|
|
physical state of compunds
|
IB solid crystals
CB solid,liquid,gas, (polarity) |
|
|
compare bond lengths and strengths
|
IB strength depends on charge and size of meatter; very strong (pack tightly together)
CB shorter bonds=stronger bonds (single is longest) |
|
|
compaire melting/boiling points of compunds
|
IB strong forces, so high melt temps and boinling temps.
CB forces between bonds are not stron, so melt and boil points are at low temps |
|
|
compaire volatillity of compounds
|
IB do not baporize at room temps
CB vaparize at room temps |
|
|
electrical conductivity of compounds
|
IB if the electrolytes are molten or dissoved,it will conduct
CB not a good conductor of electricity |
