Only if they are hydrates. Different compounds can combine with a discrete number of water molecules, such as, for example copper.
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Large mineral crystals are commonly found in igneous rocks, such as granite and pegmatite, where slow cooling allows minerals to grow large. Certain metamorphic rocks, like marble and schist, can also contain large mineral crystals due to high pressures and temperatures. Veins and pockets within rocks can sometimes host large crystals as well.
No, not all mineral crystals are made of ions. Some minerals are made up of covalent bonds or metallic bonds rather than ionic bonds. These different types of bonding arrangements can result in a variety of crystal structures within minerals.
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
No, not all extrusive igneous rocks contain visible crystals. Some extrusive rocks, such as obsidian and pumice, cool so quickly that mineral crystals do not have a chance to form, resulting in a glassy texture instead.

Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.

Mineral crystals can contain ionic bonds, covalent bonds, or metallic bonds depending on the specific elements involved in the mineral composition. These bonds help give minerals their distinctive properties such as hardness, cleavage, and color.

Yes, coal can contain crystals. These crystals are typically small and can be found scattered throughout the coal matrix. They are formed from mineral impurities present in the original plant material that formed the coal.
