Chem 2 Flashcards
(34 cards)
4 types of bonds
Ionic, Covalent molecular/network and metallic
Name 5 Ionic physical properties
Hard, conductive in soluble state, soluble, brittle, high Tm/Tb
name 5 Covalent molecular physical properties
Non-conductive, soft, brittle, low Tm/Tb, insoluble
name 5 Covalent Network physical properties
Hard, High Tm/Tb, non-conductivity, brittle, insoluble
name 5 Metallic physical properties
conductive, malleable, insoluble, hard, high Tm/Tb
VESPER Theory
V shaped, trigonal pyramidal, tetrahedral, linear and trigonal planar
Polarity
a separation of electric charge making a molecule dipole
what are the 3 Intermolecular Forces
Hydrogen-bonding, Dipole-Dipole, Dispersion
positives are attracted to what
positives attracted to negatives
what is intermolecular forces
force between molecules
What is FON and relates to what
Fluorine, Oxygen, Nitrogen and relates to Hydrogen-Bonding
What intermolecular forces can act on polar molecules
Hydrogen-Bonding and Dipole-Dipole
What intermolecular forces can act on non-polar molecules
Dispersion Force
metals conduct electricity because?
the valence electrons are not firmly bound to each atom
malleable means
that can be hammered to change shape
Covalent molecular bonding is
When valence electrons are shared
H2O is polar because
a large difference in electronegativity between hydrogen and oxygen
why can ionic bonds conduct electricity when dissolved?
ion charges become mobile when dissolved which causes flow of charge
Permanent Dipoles are called what?
Polar
Non-permanent Dipoles are called what?
Non-polar
Example of metallic bonding
Sodium, Aluminum, silver, gold or any metals
Example of Covalent molecular bonding
Oxygen, Nitrogen, hydrogen or any non-metals
Example of Covalent network bonding
Sand/glass (SiO2), Diamond/graphene (C)
Example of ionic bonding
Sodium chloride, potassium carbon, lithium fluorine or any combination of a metal and non-metal.
