A crystal system having all sides (a, b and c) unequal and angles α = β = γ = 90 is:
Correct answer: C. Orthorhombic
- A. Cubic
- B. Rhombohedral
- C. Orthorhombic
- D. Hexagonal
Explanation
This is correct because an orthorhombic system has all three sides unequal (a ≠ b ≠ c), but all angles are 90° (α = β = γ = 90°).

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.
