During the Middle Ages, it was used against the plague. Today, it is used for ailments that run from simple colds and sniffles to rheumatoid arthritis. Its effectiveness against headaches has been documented.
In summary, a crystal is any solid material with its atoms organized in a repeating pattern. There are four types of crystals. Covalent crystals occur when the atoms form strong, covalent bonds. Such crystals, like diamonds, are very tough. Ionic crystals, like table salt, are hard and stable but are made of atoms connected by electrical charges. Metallic crystals are formed from metal elements and conduct electricity well. Molecular crystals, like rock candy, are formed through hydrogen bonds and are generally weak and have a low melting point.
An ionic bond is a bond between ions with opposite charges. Cations (positively charged ions) cannot exist without anions (negatively charged ions). An electron released by an atom to from a cation must be accepted by another atom to form an anion. Cations and anions are formed in many chemical reactions by the transfer of one or more electrons from one element to another. Ionic bonds are formed by a strong attraction between positive and negative ions. Characteristics of Ionic compounds. Some important characteristics of ionic compounds are as follows. 1. Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions.
