In silicon crystal, `Si` atoms from fcc arrangement where `4` out `8 TVs` are alos occupied by `Si` atoms. `Z_(eff)` of unit cell is

In Silicon crystal silicon atoms constitutes fcc where four out of 8 tetrahedral holes are also occupied by SI atom.Calculate the total number of effective atoms in a unit cell

On crystallisation an element 'A' forms cubic crystal. The corners of the unit cell are occupied by A atoms. The coordination number of A in the unit cell-

Potassium metal has body-centred cubic crystal. The edge length of the unit cell of the crystal is 0.542 nm. Determine the radius of K atom and the volume occupied by the atoms in the unit cell.

In a face centred cubic arangement of A and B atoms, A atoms occupy the corners and B atoms occupy the face centres of the unit cell. If one of the atoms is missing from the corner in each unit cell, what is the simplest formulat of the compound?

In a solid XY, having fcc structure, X atoms occupy the comers of the unit cell and Y atoms occupy the face centres. If all the face centre atoms along one of the axes are removed, what would be the stoichiometry of the solid?

In a diamond, carbon atom occupy fcc lattice points as well as alternate tetrahedral voids. If edge length of the unit cell is 356pm, then diameter of carbon atom is:
