Crystal Lattice | MCQs

Explanation

Explanation

Crystal lattices are classified into seven crystal systems based on their unit cell geometry.

These include:

1. Cubic
2. Tetragonal
3. Orthorhombic
4. Monoclinic
5. Triclinic
6. Hexagonal
7. Rhombohedral (Trigonal)

Explanation

The repeatable entity of a crystal structure is known as a "unit cell."

Explanation

: CsCl has a body-centered cubic (bcc) structure, where each Cs⁺ ion is surrounded by 8 Cl⁻ ions and vice versa.

Explanation

Molecules held together by van der Waals forces form molecular solids.

Weak attractive forces are called Vander Waal's Forces and can be broken with little energy.

This type of attractive force occurs in the case of non-polar molecules such as H2, O2, Cl2, CH4, CO2, etc.
