Transition elements kya hota h?

1.	Transition elements kya hota h?
Answer» Properties of transition elements include: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;<br>I want 2 know about transition elements<br>Elements in which the last electron enters the d-orbitals, are called d-block elements. These elements have general outer electronic configuration (n-1)d1-10 ns0-2.\xa0Zn, Cd and Hg which have general electronic configuration, (n-1) d10ns2\xa0do not show most of the properties of transition elements. d-orbitals in these elements are completely filled in the ground state as well as in their common oxidation states. Thus, on the basis of properties, all transition elements are d-block elements but on the basis of electronic configuration, all d- block elements are not transition elements.
