If the distance between Na^(+) and Cl^(-) ions in sodium chloride crys

1.	If the distance between Na^(+) and Cl^(-) ions in sodium chloride crystal is X pm, the length of the edge of the unit cell is
Answer» 4X pm X/4 pm X/2 pm 2X pm SOLUTION :In NaCl EDGE LENGTH, (a) `= 2xx` distance between `Na^(+)` and `CL^(-)` = 2X .
