cud anyone explain me the concept of voids.....(tetrahedral and octahedral)
means i find it quite confusing ...... it just doesnt seem to go in my fat head.....
plzzzzzzzzz

FAILURE IS NOT FALLING IN LIFE BUT NOT RISING AGAIN AFTER FALLING!!!!!!
I LIKE WAVES NOT BECAUSE THEY RISE AND FALL..
BUT BECAUSE EVERYTIME THEY FALL THEY RISE AGAIN!!!!!!!

the no of octahedral voids in a unit cell = no . of atom in U.C. the no. of tetrahedral voids in a U.C. = 2(NO OF ATOM IN U.C.

look,i'll try my best to satisfy u....
first of all consider a 2d plane wid the particles arranged in such a manner dat each particle is surrounded by 6 particles.this is called hexagonal close packing.....
now there r bound 2 b sum empty spaces b\w d particles as the particles r considerd 2 b spherical.....
now,whn we considr the layer above the first 2d layer,there r two kinds of voids or empty spaces created.....
the first kind ofvoids are created whn d empty space of one layer coincides wid the empty space of the layer below,thn its calld an octahedral void...
while d second kind of void is creatd whn the void ofone layer lies on one of the particles of the layer below....
its calld a tetrahedral void
