Question

The smallest part of a crystal lattice showing all the properties of a crystal is called the ____.

Options
  • A

    Crystallite

  • B

    Unit cell

  • C

    Unit crystal

  • D

    Monomer 

Explanation

The unit cell is also known as the arrangement of the molecules that results in the shape of the crystalline substance. For example, in NaCl, Na and Cl are responsible for the arrangement of the lattice as well as the chemical properties of the lattice. 

False!A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions.
