Reduction-Oxidation Reactions
| Question | Answer |
|---|---|
| oxidation numbers | the charge an atom would develop if the MOST electronegative atoms in the molecule TOOK the electrons from the LESS electronegative atoms |
| ionic compounds | made when electrons are GIVEN up by one atom and TAKEN by another |
| covalent compounds | made when atoms SHARE their electrons |
| When atoms share electrons, they often _____ __________ share them equally. | do NOT |
| The MORE electronegative that an atom is, the _______________ the share of electrons it receives. | bigger |
| POLAR covalent molecules | when electrons are NOT shared equally, therefore developing FRACTIONAL charges |
| Oxidation numbers bridge the gap between ionic and covalent compounds by TREATING all compounds as if they were ________________ compounds. | ionic |
| Oxidation numbers aren't real, but rather are a technique that allows us to determine where _________________ travel during a chemical reaction. | electrons |
| The sum of all oxidation numbers in a molecule must _______________ the electrical charge of that molecule. | equal |
| oxidation number of a substance w/ only 1 type of atom = | the CHARGE of the substance DIVIDED BY the number of atoms present |
| oxidation number of Group 1A metals = | +1 (in molecules that contain more than 1 type of atom) |
| oxidation number of Group 2A metals = | +2 (in molecules that contain more than 1 type of atom) |
| oxidation number of Fluorine = | -1 (in molecules that contain more than 1 type of atom) |
| The oxidation number of H = +1 EXCEPT when it is grouped with | JUST 1 other atom that is a METAL, in which case it = -1. |
| oxidation number of oxygen = | -2 (in molecules that contain more than 1 type of atom) |
| If all else fails, assume that the atom's oxidation number = | the SAME as THE CHARGE it would have in an IONIC compound. Columns 3A, 6A, and 7A are most likely to follow this rule. |
| oxidation | the process by which an atom LOSES electrons |
| reduction | the process by which at atom GAINS electrons |
| LEO | Lose Electrons Oxidation |
| GER | Gain Electrons Reduction |
| When a redox reaction occurs, there will always be | at LEAST 1 atom that is oxidized and at LEAST 1 atom that is reduced. |
| Redox reactions involve the | TRANSFER of electrons. |
