The highest magnetic moment is shown by the transition metal ion with the configuration :
3d2
3d5
3d7
3d9
A transition metal ion exists in its highest oxidation state .It is expected to behave as :
a chelating agent
a central metal in a coordination compound
an oxidising agent
a reducing agent
The flame colours of metal ions are due to
Frenkel defect
Schottky defect
metal deficiency defect
metal excess defect.
Assertion : Cu(OH)2 is soluble in NH4OH but not in NaOH.
Reason : Cu(OH)2 forms a soluble complex with NH3.
