Transition Metals Flashcards
(19 cards)
Where are transition metals found on the periodic table
D block
What two metals are not transition metals that are in Dblock
Scandium and Zinc
Physical properties of metals
Malleable
Ductile
Sonerous - sound
Conduction of electricity
Lustrous
High mp and bp
Chemical properties of metals
Complex formation
Coloured ions
Variable oxidation states
Catalytic activity
What four metal are magnetic
Cobalt
Nickle
Steal
Iron
What is a transition metals
Partially filled 3D energy levels when they are an ion or an element
How does chromium electron configuration change
Due to repulsion between paired electrons in the 4s orbital which overpowers the energy between 3D and 4S
Why does copper have its electron configuration
More stable for it to have fully paired 3D and 1 that tops from 4s
How is color seen
All waves are absorbed and the colour seen is reflected
How are transition metals identifiable
By their colour
How do transition metals 3D shell split
Due to absorbing light they gain energy
Planks constant
6.63 x 10. Negative 34
Why do non transition metals not have colour.
Full or empty 3D orbitals
So they can’t split
What can affect energy change in transition metals
Coordination number
Oxidation state
Lignids bonded
Metal ion
How can you identify concentration of a transition metal
Caliometer
Complex ion
Metal ion surrounded by lignids coordinatley bonded
What shapes do complex ions form
Linear
Square planar- tetrahedral
Octahedral
Monodentate
One bonded lignin
How do lignids interact
Lone pairs
