Transition metal An element whichforms at least one stable ion
with a partiallyfilled subshell
Properties due to incomplete d subshell
variableoxidationstates
catalytic activity
formation of complexions
form coloured ions
Transition metals cuts as heterogenous catalyst
catalyst in a different state to its reactants eg Feif 1191299
Ni in hydrogenation

Add twospatulasofZinc as a reducingagent
Stopper the
