boron compounds borates

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 of this gr..

It is absorbed in the form of borate ions (BO 3 3 - or B 4 O 7 2 -..

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..

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,..

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...

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

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' orbitals are already filled. So..

Trends in Chemical Reactivity of Group 13 Elements - Unlike boron, the other members of the group are metallic and the electropositive character increases as we go down the group. All these elements in their compounds exhibit the oxidation state of + 3 and +1. The important chem..
