Metallic gold crystallizes in ccp lattice. The length of the cubic uni – InterviewSolution

1.	Metallic gold crystallizes in ccp lattice. The length of the cubic unit cell is 4.242 A^@. The closest distance between two atoms of gold
Answer» `4A^@` `3A^@` `2A^@` `6A^@` Solution :In a ccp structure the CLOSEST DISTANCE between two ATOMS `= a/(SQRT2) = (4.242)/(1.41) = 3A^@`.
