        Lanthanide

Lanthanides were first discovered in 1787 from a unusual black mineral found in ytterby , Sweden. This mineral now known as Gadolinite, and was separated later in various lanthanide element . 

  In 1795 , professor Gadolin obtained an impure from of yttrium oxide from the mineral . In 1803, Berzelius and Klaproth separated the cerium compound . Latter , Mosely using  X - ray spectra of the element showed that there were 14 element between Lanthanum and Hafnium . The rest of the element were latter separated from the same mineral , Gadolinite .

   These elements were first classified as rare earth due to the fact that obtained by reasonable rare minerals . But , this is misleading , since the lanthanide elements have a practically unlimited abundance .
So, the term , Lanthanides was adopted , originating from the first element of the series , Lanthanum .

   The Lanthanides consist of the element in the f - block of period six in the periodic table . These metals are considered as transition metals and have properties that set them apart from the rest of the element.

Siemens Ozoniser how Siemens Ozoniser work

Siemens Ozoniser:  This Ozoniser consist of two co-axial glass tubes fused together at one end. The outer side of the outer glass tube and the inner side of the inner glass tube are finally coated with tin foils as shown in the figure given below.  (Siemens Ozoniser)->2                                                     (Siemens Ozoniser)->1 These tin foil are connected  to the induction coil for supply of silent electric discharge. Pure and dry oxygen gas is passed into the apparatus through annular space. The gas is then subjected to the action of silent electric discharge where oxygen gets converted into ozone. The ozonised oxygen then comes out  of the apparatus through the outlet of the Ozoniser. (Siemens Ozoniser)->2

Rutile structure

-
Rutile structure: The radius radio is in the range 0.73 to 0.41. in rutile (TiO²) each Ti⁴+ ion is octahedrally surrounded by six O²- ions whereas each other O²- ion is surrounded by only three Ti⁴+ ions arranged at the tree corners of a plane triangle. The Co-ordination number of Ti⁴+ and O²+ ions are 6 and 3, respectively. It is not exactly a close packed structure. Ti⁴+ ions in rutile may however, be considered as forming a sufficiently distorted body centred cubic lattice.           Example  compounds  having radius ratio below 0.41 are SiO² and BeF² but these are only a few. The Co-ordination number of Si⁴+ and Be²+ is four and that of O²- is two. However, these are appreciably co-valent.

F - block element What are f - block elements

What are F - Block Elements - F - block elements are consist of Lanthanides and Actinides. In Lanthanides, they are 14 element immediately following Lanthanum (57) from cerium (58) to lutecium (71) . These 14 element are called Lanthanides . These Lanthanides belong to first inner transition series .           In Actinides , these are also 14 elements immediately following Actinium (89) starting from Thorium (90) to lawrencium (103) . The element from Th (90) to Lr (103) are called Actinides . They belong to second inner transition series.
