If the distance between Na^+ and Cl^- ions of sodium chloride crystal is 'x' pm, then length of the edge of the unit cell is

If a is the edge length of unit cell of sodium chloride, the distance between the nearest Na^(+) and Cl^(-) ions is

The following are some statements about the crystal lattice structure of sodium chloride i) If the corners of unit cell are occupied by Nation, the face edges are occupied by sodium ions ii) The ratio between radii of Na^+ and Cl^(-) ions is 0.93 iii) If the body centered ion of unit cell is Na^+ face centered ion in it is Cl^(-) The correct combination is

By X-ray diffraction method, the unit cell edge length of sodium chloride is found to be 562.6 pm. The density of NaCl is observed to be 2.158 gcm^-3 . Calculate the percentage of Na^+ and Cl^- ions missing.

NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which r_"Na"^+ and r_"Cl"^- are 95 and 181 pm respectively , where Cl^- is present at the lattice point of face centered cubic unit cell Na^+ ions are located in void and those compounds which have same crystalline structure also have same coordination system in which Na^+ and Cl^- ions are surrounded by certain number of opposite ions respectively. Under high pressure coordination number changes to 8 :8 type from 6 :6 type. On Subjecting NaCl under high pressure it changes
