Question

how can crystals be classified according to their crystal structure?
o a. three - dimensional crystals and two - dimensional crystals
o b. single crystals and polycrystals
o c euhedral crystals and subhedral crystals
o d. liquid crystals and solid crystals

Explanation:

Crystals can be classified into single crystals, which have a continuous and unbroken lattice structure throughout, and polycrystals, which are composed of many small crystals (grains) with different orientations. This is a common way of classifying crystals based on their structural nature.

Answer:

B. Single crystals and polycrystals
