  • Front
  • Back
Battery Capacity
the amount of electrons (the total charge) it can deliver
Oxidation is and occurs in
loses an electron; anode
Reduction is and occurs in
gains an electron; cathode
Metal to Metal Reaction
Metallic Bonding
Non-Metal to Non-Metal Reaction
Covalent bonding
Non metal to metal reaction
ionic compound
Covalent bonding
electron sharing
Ionic Bonding
Electron transfer
Metallic bonding
electron sharing
electronegativity
the tendency of an atom to attract electrons to itslef
metal atoms
excess electrons; poor electronegativity
non metal atoms
lack electrons; high electronegativity
electronegativity on the periodic table
increases from left to right, decreases from up to down
shielding
tendency of inner shell electrons to diminish the attraction of outer valence electrons to nucleus; shielding weakens electronegativity
Solid Ionics
high melting, hard, brittle, crystalline, non-conductive of electricity
Oxidation Reduction Reactions (Redox)
Reactions involving electron transfer
Voltaic Cell
produces a positive voltage; electrons flow from anode to cathode; ions complete circuit thru salt bridge
Electrolytic reaction
negative voltage; non spontaneous; foreced to run using external power source
electrolysis
used for two purposes: 1) recharging voltaic cells (batteries) 2) producing materials (including electroplating)
Buckyballs
ultimate nano-ball bearing; conductive particles; can trap an atom inside; no real uses yet
