The chemical element germanium, with the symbol Ge and atomic number 32, is a grayish-white metalloid. It is located in the carbon group of the periodic table and is similar in physical and chemical properties to silicon, its groupmate.

Germanium was discovered by German chemist Clemens Winkler in 1886, while he was studying the minerals argyrodite and silver sulfide. However, it was not until after World War II that germanium became important due to its semiconducting properties, which made it useful in the development of transistors and other electronic devices.

In terms of its physical properties, germanium is a brittle, lustrous, hard metalloid with a metallic appearance. It has a melting point of 937°C and a boiling point of 2830°C. It is a poor conductor of electricity at room temperature, but its conductivity increases as the temperature increases.

Germanium has several important chemical properties. It is highly reactive with oxygen and reacts with water to form germanium hydroxide. It is also resistant to attack by most acids, but it will dissolve in concentrated sulfuric acid and hydrochloric acid.

Germanium has several important industrial uses. It is used as a semiconductor in the production of transistors, diodes, and other electronic devices. It is also used as a catalyst in the production of certain chemicals and in the purification of certain substances.

In addition to its industrial uses, germanium has some medical uses as well. It has been shown to have anti-inflammatory properties and has been used in the treatment of certain types of cancer. It has also been used to treat certain types of heart disease and has been shown to have immune system-boosting properties.

Overall, germanium is an important chemical element with a variety of industrial and medical uses. Its semiconducting properties have made it essential in the development of electronic devices, and its other properties make it useful in a variety of other applications.

What is Germanium

Progress in Photovoltaics: Research and Applications. In the second half of the twentieth century, physics laboratories became able to produce nuclei of chemical elements with half-lives too short for an appreciable amount of them to exist at any time. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. Bulletin for the History of Chemistry. Germanium, symbol Ge, has a Face Centered Cubic structure and Gray color. The chemical symbol for Chromium is Cr. Uses Germanium first became important for its use in semiconductors.

Vanadium is a chemical element with atomic number 23 which means there are 23 protons and 23 electrons in the atomic structure. Adding a heat will convert the solid into a liquid with no temperature change. Iron is a metal in the first transition series. Four tetra 4 is a solid, GeF 4 a gas and the others volatile liquids. Electronegativity Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state.

Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure. However, more energy is required to add an electron to a negative ion which overwhelms any the release of energy from the electron attachment process. Inhalation risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. Germanium is also used to make specialized glass for military applications. Germanium is also used as a catalyst.

The first two columns on the left side of the periodic table are where the s subshells are being occupied. Mendeleyev's Dream: The Quest for the Elements. Such weak intermolecular bonds give organic molecular substances, such as waxes and oils, their soft bulk character, and their low melting points in liquids, molecules must cease most structured or oriented contact with each other. International Journal of Modern Physics E. In a neutral atom there are as many electrons as protons moving about nucleus. Increasing the pressure on an material especially for liquids or gases decreases the volume of the object and thus increases its density via the atomic number density.
