NH4Cl crystallizes in a body-centred cubic lattice with an edge length of the unit cell equal to 387 pm. If the radius of the Cl− ion is 181 pm, the radius of the NH4+ ion is:
Correct answer: A. 154.1 pm
- A. 154.1 pm
- B. 92.6 pm
- C. 366.3 pm
- D. None of these
Explanation
In body centred cubic lattice, oppositely charged ions touch each other along the cube.

About Solids
Solids are classified by particle arrangement and bonding into crystalline, ionic and molecular forms. Questions cover crystal lattices, the shapes and properties of ionic crystals, and lattice energy, including how ion charge and ionic size affect the strength of attractions within an ionic solid.
