Beryllium is a soft metal that is widely used in X-ray equipment and aerospace applications. In nuclear reactions, it is used as a moderator and as a reflector. It is also used in computer parts and gyroscopes.
It is often combined with other halogens to make compounds. In addition, its melting point is quite high. Iodine, on the other hand, is a halogen. However, its electronegativity is less than that of chlorine. So, the two together can form an ionic compound.
The chemical formula of the beryllium ionic compound is BeI2. It has a high charge-to-size ratio, which makes it highly brittle. This explains its use in x-ray equipment and gyroscopes. Other applications include computer parts and a reflector in nuclear reactions.
The elemental form of beryllium is a gray metallic material. It is highly soluble in water. Several minerals contain beryllium.
The iodine ion forms a blue complex. It is one of the largest monatomic anions. There are several oxidation states of the iodine ion. These oxidation states range from -1 to +3 to +5. A cyanogen is produced at red heat.
A-iodination of carbonyl compounds is a process that can be performed by a direct treatment of the enolate ion with elemental iodine. Alternatively, it is possible to a-iodinate carbonyl compounds through a reaction with a covalently bound C2 chiral auxiliary.
The iodine cation has a radius of approximately 206 picometers. It has a high degree of solubility in most metals and is commonly used in organic chemistry.
