Short Answer TypeCalculate the number of unpaired electrons in following gaseous ions: Mn3+, Cr3+, V3+ and Ti3+, which one of these is the most stable in aqueous solution?
Give example and suggest reasons for the following features of the transition metal chemistry:
The lowest oxide of transition metal is basic, the highest is amphoteric/acidic.
Give example and suggest reasons for the following features of the transition metal chemistry:
A transition metal exhibits highest oxidation state in oxides and fluroides.
Give example and suggest reasons for the following features of the transition metal chemistry:
The highest oxidation state is exhibited in oxoanions of a metal.
Inner transition metals are those elements in which the last electron enters the f-orbital also transition elements are the elements which have partly filled f-orbitals. These are also called f-block elements. There are two series (each of 14 elements) of inner transition elements..
(i) Lanthanoids (also called 4f series). These are from atomic numbers 58-71.
(ii) Actinoids (also called 5f series ). These are from atomic numbers 90-103
Among the given atomic numbers, only 59, 95 and 102 are the atomic numbers of inner transition elements. The other three atomic numbers represent the transition elements.
