SAMPLE NO: 2 OTHER DETAILS: General Characteristics of Iridium Trichloride elements. Some important characteristics of 3d-series elements are describes as follows: METAL CHARACTER: All the transition elements are metals, since the number of electrons in the outermost shell is very small, being equal to 2. They are hard, malleable and ductile. They exhibit all the three types of structures: Face Centered Cubic (FCC), Hexagonal Close Packed (HCP), and Body Centered Cubic (BCC), METLS of vii and IB Groups are softer and more ductile than other metals. It appears that covalent and metallic bounding both exist in the atmos of transition metals. The presence of unfilled-Orbital’s favours covalent bonding. These metals are good conductor of heat. Atomic volumes and densities, the atomic volumes and densities of the elements of 3d-series are given below: Elements: SC TI V CR MN FE CO NI CU ZN Atomic Vol 15.0 1.66 8.3 7.2 7.3 7.1 6.7 6.6 7.1 9.2 UMW(Cm) Density (G/CM2) 3.0 4.5 6.1 7.2 7.4 7.8 8.9 8.9 8.9 7.1 |
For Example:
(A) T14+(3D0,480) is more stable than T13 + (3D1,480), because of the presence of 3D0 orbital in T14 + 10N(B) Mn2 + (3D5,480) is more stable than Mn3 + (3D4,480), is more stable than Mn3 + (3D4,480), since Mn2 10N has 3D5 orbital (C) AG+(4D0,580) is more stable than Ag2 + (4D9,580) because of the presence of 4D 10 AG+ (4D0,580) is more stable than Ag2 + (4D9,580) because of the presence of 4D10 orbital in AG+IR (VI) transition elements can from Ionic bonds in their lower Iridium States and the iridium char acter of the bond decrease (or convalent char acter of the bond increases) with the decrease 0 of Ionic character. The Acidic character of oxides fro example: A) With the decrease of the Iridium Character of M-O Bond in the Oxides, the acidic character of the Oxides increase as shown below:- |

B) With the Decrease of the Iridium Character of M – C1 Bond
in the Chlorides, the Acidicx Character of the Chlorides Increases as show
below:
Generally the melting and boiling points of D-Block elements increase on descending a group. Melting and Boiling points of AG are lower than those of CU and AU. This can be explained on the basis that both CU and AU have greater tendency to acqure higher Oxidation state than +1, suggesting that in these metals the invoement of D-Orbital for metallic bonding is to greater extent than in AG Z. III) On descending a group n increases. The Atomic size is therefore, expected to increase from top to bottom. But this increase is not the same for all the members. The difference in Iridium of the second and third series elements is very small (‘0.02 A0) as compared to the first and second series members. This is due to the Lanthanide contraction due to the inclusion of 14 Lanthanides between LA (Z=57, group=IIIB) and HF (Z=72, group IVB), HF is not as large as it would have been, 1F it had followed directly after LA. The Nuclear charge in the second series members are 18 units greater than the first series members, but this difference between the 2nd and 3rd series elements 1S 32 thus, the increase in n (from 2nd series (N=5) to 3rd series (N=6), though tends to increase the size. The excessive increase in nuclear annuls this effect. Consequently the elements of 2nd and 3rd series are very similar in size. IRIDIUM The Iridium follow the same trend as the Atomic Iridium. It may be seen that the Iridium of the Ions having the same charge (valency) decrease with increase in Atomic number.
