The crystal having hcp is A_2B_3. Which atom hashcp structure and by other molecules of tetrahedral voids how much space is occupied ?

Answer»

hcp crystal - A, `2//3` TETRAHEDRAL VOIDS - B 
hcp crystal - A, `1//3`, Tetrahedral Voids - B 
hcp crystal - B, `1//3` Tetrahedral Voids - A 
hcp crystal - A, `2//3` Tetrahedral Voids - A 

Solution :If hcp crystal is`to`B, then tetrahedral voids are OCCUPIED by P.
