Which characteristic properties are shown by d-block elements? Why? |
|
Answer» Solution :The following characteristic properties are shown by d-block elements: (i) Variable oxidation states. (ii) FORMATION of coloured compounds. (iii) Formation of complex compounds with variety of ligands. (iv) Paramagnetism and catalytic activity (v) Alloy formation The characteristic properties of these elements is because of incompletely filled d-orbital that are PROJECTED to the periphery of an atom more than s- and p-orbitals. As a result, ATOMS of these elements are more influenced by surroundings as well as by the atoms surrounding them. This also results in GREATER similarity in the properties of TRANSITION elements of horizontal row in contrast to non-transition elements |
