Gen Chem Intra-Inter

• three- dimensional arrangement of particles, a repetitive pattern. Crystal lattice
• No definite or defined structure/form. Amorphous Solid
• More then one form depending on structure of carbon. Allotropes
• Irregular pattern, melt over a range of tempt, no definite heat fusion, glass, called isotropic. Amorphous
• Regular repeating pattern, sharp melting point, definite heat fusion, glass, called anisotropic. Crystalline
• act within molecules, strong, persist for life of molecule, not strongly effected by physical changes, stabilize individual. Intramolecular Forces
• weak, act between molecules, more brief in life of molecule, strongly effected by physical changes, responsible for bulk properties of matter. Intermolecular Forces
• boiling point, melting point, viscosity, surface tension, capillary action. physical changes/properties
• the more polar molecules are, the stronger intermolecular forces are.
• how a non polar particle can be temporarily polarized. Dispersion Forces
• tendency of an electron cloud to distort. polarizability
• number of electrons in atom, size of atom or molecule, shape of molecules with similar masses. factors affect amount of dispersion force in molecule
• polar molecules have more positive and more negative end, oppositely charged ends attract each other. dipole-dipole interactions
• when h is bonded to N,O or F are unusally strong, an attraction between a hydrogen atom attached to a highly electronegative atom. Hydrogen bonds
• found in solutions of ions, ionic substances dissolve in polar solvents. Ion-dipole interactions
• Dipole-dipole interactions, ion-dipole interactions, hydrogen bonding, london dispersion force. Intermolecular Forces
• Covalent bond, ionic bond, metallic bond. Intramolecular forces
• referred to as the condensed phases. Solids and liquids
• Have definite volume and assume the shape of its container, Much denser than gases, difficult to compress than gases. liquid
• Almost uncompressible, Definite shape and volume , Most solids are denser than liquids. Solid
• smallest group of particles within the crystal that retains the geometric shape of the crystal. Unit cell
• a repeating pattern of unit cells. crystal lattice
• If something is easier to polarize, it has a lower boiling point.
• 0-0.5 Non polar covalent bond
• 0.6-2.0 Polar covalent bond
• 2.1 above. Ionic Compound
• DETERMINES WHETHER OR NOT ELECTRONS IN THAT MOLECULE ARE SHARED EQUALLY. Polarity
• polar. Asymmetric
• non polar. symmetric
• THE MOLECULE IS NON-POLAR AND THERE ARE NO UNBONDED ELECTRON PAIRS, HAS THE SAME POLARITY AND THERE ARE NO UNBONDED ELECTRON PAIRS ON THE CENTRAL ATOM, NO NET DIPOLE MOMENT. Non polar
• net dipole moment, THE MOLECULE IS NON-POLAR, BUT THERE ARE UNBONDED ELECTRON PAIRS ON THE CENTRAL ATOM. Polar
