Transition elements

Read our general notes on Risk Assessment

In an advanced level course you only have to study the first-row d-block elements from scandium to zinc. You will discover that chemists make subtle distinctions so they typically exclude scandium and zinc and only regard the other eight elements as transition elements.
 
Transition elements are characterised by:

their electron configurations,

their physical properties,

their variable oxidation states,

the colour of many of their compounds,

the tendency for the metal ions to form complexes,

the catalytic activity of the metals and their compounds.

• I want to design an experiment to identify the percentage of copper in a given copper compound using a titration method. How do I do this? 270110
• 'The d-block elements are less reactive than the s-block elements because 'inner' d orbitals are being filled while the 'outer' s subshell is full.' I know that the 4s orbital has a lower energy than the 3d orbitals. So doesn't that mean the 4s orbital is 'closer' to the nucleus than the 3d orbitals? The above information is confusing me. Please help. 181209
