If the distance between Na+ and CI– ions in NaCl crystal is a pm, what is the length of the cell edge?
- 2a pm
- a / 2 pm
- 4a pm
a/4 pm
The tetrahedral voids formed by ccp arrangement of CI– ions in rock salt structure are:
- Occupied by Na+ ions
- Occupied by CI– ions
- Occupied by either Na+ or CI– ions
- Vacant
Most crystals show good cleavage because their atoms, ions and molecules are
- Weakly bonded together
- strongly bonded together
- spherically symmetrical
- arranged in planes.
CsCl has which type of lattice?
