boron compounds

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,..

Boric acid may also be obtained by the hydrolysis of most boron compounds like nitrides, sulphides, halides etc...

Boron hydrides (or boranes) - 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 ..

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...

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..

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

1. Boron is a non-metal whereas aluminium is a metal. 2. Boron is a bad conductor of electricity whereas aluminium is a good conductor. 3. Boron exists in two forms-crystalline and amorphous. Aluminium is a soft metal and does not exist in different forms. 4. The melt..

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. Some of t..

The elements of group 1, 2 and 13 contain less than four electrons in their valence shell. An octet cannot be achieved by electron sharing for these elements. As a result, elements of these groups should not ordinarily form covalent compounds, but some elements do. Boron halide..

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 +..
