Question number 31
@Churchil_Dwivedi @fog856 @Unik-Wadhwani
Please help. Nt getting.. what the ques says..
option number 1
It would require too much imagination..will think about it at night.
question number 34
Realised my mistake before only...b should be correct.
If no of atoms is halved...pf is halved
34 for bcc
37 for hcp
Percent of voids
I find question 31 too difficult even to think about it.
Because it actually need that much imagination.
i tried a a lott.. 31 n left it then
1 cn 6 face centers
2 cn 12 edge centers
3 cn 8 corners
4 cn 6 adjacent unit cell body center with distance a
5 cn 24 adjacent unit cell face center with distance (5)^1/2 a / 2
6 cn 24 adjacent unit cell edge center with distance (3/2)^1/2 * a
unable to understand the question! What does it mean by 3rd coordination number and 6th coordination number?
coordination number is defined as the number of atoms which are nearest neighbour to one particular atom.
1 cn = nearest neighbour
2 cn = next nearest neighbour
3 cn = next to next nearest neighbour
and so on...
Thanks @Pravina_Sawaliya Got it !
