Electronic Configuartions nd Oxidstion States Of Transistion Metals Flashcards
What does [Ar] rep
1s^2 2s^2 2p^6 3s^2 3p^6
What are d block transition metals
Metals with an incomplete d orbital in at least one of their ions
When a transition metal atom forms an ion what is lost first
The 4s electrons are lost before the 3d ones
The oxidation state of a nun combined element is
0
In most compounds hydrogen gas has a num of
Hydride is num of
Hydrogen is +1
Hydride is -1
For ions that are monatomic ( Na Cl )
Oxi num is the same as the charge of the ion
In most compounds oxygen has a num of
-2
In compounds fluorine has a num of
-1
The sum of all the oxi mums must be equal to
0
Sum of all oxi mums on oolyatomic ions must add up to
Charge on the ion
Oxidation can be redefined to an
Increase in oxi number
Reduction can be redefined as a
Decrease in oxidation number
Give an example of a good oxidising agent
Acidified permanganate
