The chemistry of actinoids is more complicated as compared to lanthanoids?

Lanthanoids show a limited number of oxidation states due to the large energy gap between 4f and 5d subshells.

-

-

Actinoid elements have several other oxidation states.

(Continues...)

Actinoids are mostly present in small quantities and their half-life is extremely small.

-

-

Because they are mostly radioactive, it is difficult to study their characteristics.

Transition metals form complex compounds?

They can accept electron pairs from Lewis bases.

 -

 -

Transition metal ions can form coordination complexes because their valence shell orbitals are vacant.

Complete the following equation 2MnO + 6H + SO →

2MnO   +6H + SO  →  2Mn  + 5SO  + 3H O
