boron compounds element

Boron - Boron (B) is the first member of group 13 of the periodic table and is the only non-metal of this group. It has an electronic configuration of 1s 2 2s 2 2p 1 with only three electrons in its valence shell. Dissimilarities of boron with other elements ..

Boron can be obtained by the electrolysis of fused mixture containing boric anhydride (B 2 O 3 ), magnesium oxide (MgO) and magnesium fluoride at 1100C. The reactions taking place during electrolysis are,..

By reducing volatile boron compound (boron trichloride) by dihydrogen at high temperature, boron is obtained. ..

The hydrides of boron are known by a general name borane. These boranes are gaseous substances at room temperature. The general formulae of the two important series of boranes are B n H n + 4 and B n H n + 6 . Amongst the well known boron hydrides are: diborane (B 2 H..

Introduction - Elements of group 13 to 18 of the periodic table are collectively called 'p' block elements. The general electronic configuration of these elements is ns 2 np 1 - 6 . They involve the filling up of 'p' orbitals of their outermost shells, when their 's' o..

Solution - In NF 3 nitrogen involves sp 3 hybridisation and one position is occupied by a lone pair. Therefore the molecule is pyramidal. But in BF 3 , B involves sp 2 hybridisation having triangular planer geometr..

Borax (Na 2 B 4 O 7 .10H 2 O) - Borax occurs naturally as tincal (contains about 55% borax) in certain inland lakes of India, Tibet and California (U.S.A...

Other boron halides can be prepared by the action of halogens and boron oxide in the presence of carbon. Boron triodide (BI 3 ) is prepared by the action of iodine on sodium borohydride..

Group 13 of the periodic table consists of the elements boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl). Except boron, which is classified as a non-metal, all other elements of this group are metal..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing, and produ..
