Trivia quiz questions with answers about crystals

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged how?
A: In a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

In addition, macroscopic single crystals are usually identifiable by what?
A: Their geometrical shape, consisting of flat faces with specific, characteristic orientations.

The scientific study of crystals and crystal formation is known as what?
A: Crystallography.

What is the process of crystal formation via mechanisms of crystal growth called?
A: Crystallization or solidification.

Examples of large crystals include what?
A: Snowflakes, diamonds, and table salt.


Most inorganic solids are not crystals but what?
A: Polycrystals, i.e. many microscopic crystals fused together into a single solid.

Examples of polycrystals include what?
A: Most metals, rocks, ceramics, and ice.

A third category of solids is amorphous solids, where the atoms have what?
A: No periodic structure whatsoever.

Examples of amorphous solids include what?
A: Glass, wax, and many plastics.

By volume and weight, the largest concentrations of crystals in the Earth are part of its what?
A: Solid bedrock.


As of 1999, the world's largest known naturally occurring crystal is what?
A: A crystal of beryl from Malakialina, Madagascar, 18 m (59 ft) long and 3.5 m (11 ft) in diameter and weighing 380,000 kg (840,000 lb).

Some crystals have formed by magmatic and metamorphic processes, giving origin to what?
A: Large masses of crystalline rock.

Most igneous rocks are formed from molten magma and the degree of crystallization depends on what?
A: Primarily on the conditions under which they solidified.

What is polymorphism?
A: The ability of a solid to exist in more than one crystal form.

For pure chemical elements, polymorphism is known as what?
A: Allotropy.


For example, diamond and graphite are two crystalline forms of what?
A: Carbon.

Polymorphs may have wildly different what?
A: Properties.

For example, diamond is among the hardest substances known, while graphite is what?
A: So soft that it is used as a lubricant.

An ideal crystal has every atom in a what?
A: A perfect, exactly repeating pattern.

However most crystalline materials have a variety of crystallographic defects, places where the crystal's pattern is what?
A: Interrupted.

In semiconductors, a special type of impurity, called a dopant, drastically changes the crystal's what?
A: Electrical properties.
