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

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 `Na^(+)VL^(-)`CRYSTAL, Edge LENGTH of UNIT cell =`2times"Distance between" Na^(+) and Cl^(-)`ion 2X pm
