what are the pecularity of d block elements ?
Characteristics of d-block elements :
(i) The d-block elements are metals having high melting and boiling points .
(ii) The d-block elements exhibit transitional behaviour intermediate between highly reactive electropositive alkali metals and the covalent compound forming elements. Therefore ,the d-block elements are called transition elements .
(iii) These elements have valence electrons both in their outermost and second outermost shell and they take part in chemical reactions .So they show variable oxidation states .
(iv) Most of the d-block elements form coloured compounds .
(v) Due to the presence of one or more unpaired electrons present in the atoms or ions, these elements are generally paramagnetic .
(vi) Most of the d-block elements are good catalysts .
