Card Set Information
What type(s) of motion does matter in the solid state exhibit?
What type(s) of motion does matter in the liquid state exhibit?
Rotational & Vibrational
What type(s) of motion does matter in the gaseous state exhibit?
Translational, Rotational & Vibrational
Define Chemical Properties & give an ex.
breaking of bonds between atoms and them forming new bonds between these same atoms
define physical properties & give an ex.
changes in bonds between molecules not between atoms within molecules.
What are Dipole Attractions & an ex.
when a molecule has covalent bonds with a significant electronegativity difference
results in high melting and boiling points
ex. HCl, H2S
What are Hydrogen Bonds & 1 ex.
when a molecule has covalent bonds with a very significant electronegativity difference (N,O,F)
very high melting and boiling points
What are Van der Waals Forces (L.D)
when a molecule has covalent bonds with very low electroneg difference or none at all
low melting and boiling points
What are Covalent Bonds & an ex.
Non-M bond with Non-M
low electroneg difference
localized bonding ex. CH4
What are Ionic bonds and an ex.
Non-M bond with M
higher electroneg difference then covalent bonds
results in crystals of oppositely charged units
What are Metallic Bonds & an ex.
M - M
extremely low electroneg, therefore el- flow through the crystal
results in crystals which conduct and are malleable
