(L17) - M2 L7 - Electron Transfer Reactions Flashcards
What is a redox reaction?
Electron transfer equation
Electron transfer results in change of electron ownership of atoms involved
What can be used to keep track of electron ownership?
Oxidation number (ON)
What does monatomic mean?
Consisting of one atom
How does oxidation number relate to charge for monatomic species.
For monatomic ions, the Oxidation Number (ON) and overall charge are the same.
These are related to position in periodic table.
What is a binary compound?
Contains 2 elements
What is polyatomic?
More than 2 atoms
What is an ion?
An atom/molecule that has a net charge that’s either positive or negative
What is sum of ON of charged molecule equal too?
The overall charge.
What is ON of metallic substances like?
Always positive
Compounds containing two atoms, one of which is a metal, and the other is a non-metal, which has a
-ve oxidation number?
compounds containing two atoms, one of which is a metal, and the other is a non-metal, the non-metal must have a negative oxidation number
What is electronegativity?
Measure of the extent to which a bonded atom attracts electrons to itself.
What is an ionic compound?
Compound made up of 2 ions
Loss of an e-?
Oxidation
Gain of en e-?
Reduction
What is a oxidising agent
is reduced.
allows other ion to be oxidised.
by accepting its electrons.
