1.3 Transition Metals Flashcards
D block transition metals
Metals with an incomplete D sub shell in at least one of its ions
Metals with an incomplete D sub shell in at least one of its ions
D block transition metals
What elements are exceptions to the aufbau profile in the d orbitals
Chromium and copper
What principle are chromium and copper exempt from
Aufbau
Why are chromium and copper exempt from the aufbau principle
The special stability associated with d subshell being half or completely filled
When atoms from the first row of transition elements from ions, where does it or lose elections from
4s rather then 3d
When do elements from the first row of transition metals lose 4s electrons first rather than the 3d electrons
When they form ions
When of an element said to be in a particular oxidation state
When it has a speciation oxidation number
Oxidation number of uncombined elements
0
Oxidation number of ions containing single atoms
Same as charge on ion
Oxygen oxidation number
-2
Hydrogen oxidation number
+1
The sum of all the oxidation number of all the atoms in a neutral compound
0
The sum of all the oxidation number of all the atoms on a polyatomic ion
Must equal the charge on the ion
Does a transition metal have the same oxidation state in all its compounds
It can have different
