Question

Compare the general characterisitcs of the first series of transition metals

Answer 1

Answer:

have large charge/radius ratio;

are hard and have high densities;

have high melting and boiling points;

form compounds which are often paramagnetic;

show variable oxidation states;

form coloured ions and compounds;

form compounds with profound catalytic activity;

Answer 2

Heya Mate........

In the first transition series, 3d orbitals are progressively filled whereas, in second and third transition series, 4d and 5d orbitals are filled. +2 and +3 oxidation states of first transition series elements are more stable than +2 and +3 oxidation states of second and third transition series elements.

Hope this will help you.....
