Transition Metals Flashcards
What block are transition metals found in
d block
Transition metal definition
Has an incomplete d sub shell (excluding zinc and copper
Why does 4s orbital fill before 3d orbital?
4s is lower energy so fills first fully in accordance with the aufbau principle.
Except copper and chromium which have a half fill 4s sub shell in ground state
3 main characteristics of a transition metal -
Aside from Sc and Zn:
Can produce ions with different valencies
Can produce coloured compounds
Can act as catalysts
When removing electrons where are the electrons always removed from first?
The 4s subshell
When d - subshell is completely full what type of stability is it
Extra
Oxidation state of hydrogen and oxygen
Hydrogen +1
Oxygen - 2
Oxidation can be defined as
An increase in oxidation number
Reduction can be defined as
A decrease in oxidation number
