Unit 3 Flashcards
(25 cards)
Oxidation
Loss of electrons OR oxidation state becoming more positive
Standard Electrode Potential (E delta)
The potential difference when any half-cell is connected to the standard hydrogen electrode under standard conditions
Amphoteric
A substance that can react with both acids and bases
Inert Pair
ns2 pair of electrons not involved in bonding
Co-ordinate Bond
Shared pairs of electrons both from the same atom
Dimer
A species created when two molecules join together
Electron-deficient
A species with fewer that 8 electrons in it outer shell, thus this shell is not full
Lone Pair
Pair of electrons in an outer shell that are not involved in bonding
Isoelectronic
Same number of electrons in the outer shell
Acidic Oxide
Oxide that reacts with bases
Basic Oxide
Oxide that reacts with acids
Disproportionation
A reaction where atoms of the same element become oxidise-=][ and reduced to form two different products
Reduction
Gain of electrons OR oxidation state becoming negative
Transition Element
Element with a partially filled d-orbital in their atoms or ions
Ligand
A small molecules with a lone pair that can bond to a transition metal ion
Complex
Ligands joined to a transition metal by co-ordinate bonds
Monodentate
Ligand that has one atom that can bond to a metal ion
Bidentate
Ligand that has two atoms that can bond to a metal ion
Rate Equation
k [A]m[B]n
Reaction Order with a respect to [A]
m
Overall Reaction Order
m+n
Rate Constant
k always written as a lower case
Rate Determining Step
The slowest step in the reaction mechanism
Acid
H+ ion donor (proton donor)
