FILL IN THE BLANKS 1. _____________ are those elements that have Chapter 6 - Transition Elements Testially fileld d-or f acb shell in atomic state or any common oxidation state. 2. Zn, Cd and Hg exhibit only one property of transition elements that is _____________. 3. In a transition series, melting points _________ upto the middle of the series, and then _______ till the end of the series. 4. Fe+3 and Mn+2 are strongly para magnetic as they both have _________ unpaired electrons. 5. A metal atom or ion surrounded by a number of ligands is called ___________. 6. The central metal atom or ion alongwith ligands is called _________________. _____________ are those elements that have partially fileld d-or f acb shell in atomic state or any common oxidation state? Zn, Cd and Hg exhibit only one property of transition elements that is? _____________?
In a transition series, melting points _________ upto the middle of the series, and then _______ till the end of the series? A metal atom or ion surrounded by a number of ligands is called ___________? The central metal atom or ion alongwith ligands is called _________________? ____________ is a complex formed when ploy dentate ligands coordinate with the same metal atom or ion forming one or more ring structures? Suffix ‘ate’ comes at the end of the name of metal if the complex is ______________? Stag contains ___________, so it is ground to powder and sold as fertilizer? Oxides carbon and sulphur being volatile escape as gases, while those of _________ & _________ from slags? The process of chemical decay of metals due to action of surrounding medium is called ______________? Dichromates are powerful______________ agents?
Oxidation state ___________ is exhibited by nearly all outer transition elements? Transition elements are named so because their properties are in transition from metallic elements of s-block to the nonmetallic elements of the P-block? The ions and compounds of transition elements are coloured in solid as well as solution form at least in one of their oxidation states? In any transition series the number of unpaired electrons in the atom increases from zero to five and then drops to zero at the end of the series? Decrease in the number of unpaired electrons leads to increased diamagnetism?
