Question

What type of crystal is halite crystal (rock salt)?

Answer 1

Halite crystals are isometric crystals, meaning that unit cells of the crystal are cube shaped, which is why they're also called cubic crystals.

Answer 2

Halite crystals are isometric in nature with a cube, being their unit cells.

Further explanation:

Crystal structure or lattice is the three-dimensional representation of atoms and molecules arranged in a specific manner. The unit cell is the tiniest part of the lattice that is repeated in all directions to yield the crystal lattice. There are 3 major types of cubic unit cells as follows:

1. The simple cubic unit cell (sc)

2. Body-centered unit cell (bcc)

3. Face-centered unit cell(fcc)

Halite is also known as rock salt, sea salt or table salt. It is composed of sodium chloride (NaCl). NaCl is an ionic crystalline compound made up of  ${\text{N}}{{\text{a}}^+}$ and ${\text{C}}{{\text{l}}^-}$  ions.

Coordination number is the number of ions surrounding an ion of opposite charge. Each ${\text{N}}{{\text{a}}^+}$  is surrounded by 6 ${\text{C}}{{\text{l}}^-}$  ions and vice-versa. So the coordination number of both ${\text{N}}{{\text{a}}^+}$  and ${\text{C}}{{\text{l}}^-}$  ions in the structure of NaCl is 6.

Halite crystals are isometric crystals. This is because they have their unit cells in the form of a cube. Due to this reason, halite crystals are also known as cubic crystals.
