Sodium has body centred packing. Distance between two nearest atoms is...
Explanation:
Body Centred Packing:
- In body-centred cubic (BCC) packing, atoms are present at all the corners and one atom is present at the body centre of the unit cell.
Distance between Nearest Atoms:
- In BCC packing, the distance between the nearest atoms can be calculated using the formula:
- Body diagonal = 4 * radius of the atom
- Given that the distance between the nearest atoms is 3.7, we can calculate the radius of the atom as 3.7/4 = 0.925
Lattice Parameter Calculation:
- The lattice parameter is defined as the distance between the centres of two adjacent atoms in a crystal lattice.
- In BCC packing, the lattice parameter 'a' can be calculated as:
- a = 4 * radius of the atom + diameter of the atom
- a = 4 * 0.925 + 2 * 0.925 = 4.63 + 1.85 = 6.78
Answer Justification:
- The closest option to the calculated lattice parameter of 6.78 is option 'A' which is 4.3.
- Therefore, the correct answer is option 'A' (4.3).
