Germanium

Germanium has 36 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding.

A germanium atom has 4 valence electrons. Germanium is in Group 14 of the periodic table, so it has 4 electrons in its outermost shell.

Germanium typically gains or loses electrons to achieve a stable electron configuration. It can either accept or donate electrons to fill its outermost electron shell. Germanium most commonly forms covalent bonds by sharing electrons with other atoms.

Germanium atoms are hold together through covalent bonds, although they have more metallic character than carbon and silicon.

The density of germanium is approximately 5.32 grams per cubic centimeter.

The depletion region in germanium is small because germanium has a lower band gap compared to silicon. This results in a higher charge carrier concentration and a narrower depletion region. Additionally, germanium has a higher intrinsic carrier concentration, leading to a smaller depletion region.

The chemical formula for germanium is Ge, and for fluorine, it is F2.

Silicon Germanium Gallium Arsenide (SiGeAs) is a semiconductor material that combines silicon, germanium, gallium, and arsenic. It is used in high-frequency applications due to its superior electron mobility.

Silicon Carbide (SiC) is a compound semiconductor made of silicon and carbon. It has excellent thermal conductivity and can operate at high temperatures, making it ideal for power electronics and high-temperature applications.

LEDs are made from binary semiconductors (e.g. gallium aluminum indium phosphide) not unary semiconductors (e.g. silicon, germanium) because they can be made transparent to light. Silicon & germanium are opaque.

1064 degrees Celsius is equivalent to 1337 Kelvin, which is higher than the melting point of germanium (1210K). Therefore, germanium would melt first.

The electron configuration of germanium is [Ar] 3d^10 4s^2 4p^2, where [Ar] represents the electron configuration of argon (1s^2 2s^2 2p^6 3s^2 3p^6). Germanium has 32 electrons.

Germanium is found in trace amounts in various minerals such as germanite, argyrodite, and sphalerite. It can also be found in coal deposits and some soils. However, natural sources of germanium are limited, and most commercial germanium is produced as a byproduct of zinc ore processing.

Germanium has 32 electrons in its electron cloud.

The formula for germanium carbonate is GeCO3, where Ge represents the element germanium and CO3 represents the carbonate ion.

Germanium occurs naturally in trace amounts in certain minerals such as germanite, argyrodite, and germanium oxide. It can also be found in coal deposits and zinc ores. Commercially, germanium is primarily produced as a by-product of zinc refining.

• higher maximum operating junction temperature of 150C vs. only about 60C.
• easier to process.
• both oxide & nitride are stable solid insoluble insulators.
• higher switching speed.

Germanium-73 has 41 neutrons. This is calculated by subtracting the atomic number (32) from the atomic mass (73).

There are 4 stable natural isotopes of Ge: 70, 72, 73 , 74. 76Ge (also a natural isotope, 7,44 %) has longest half-life of all known radioisotopes as well.

Of course, the artificial isotopes are unstable.

A germanium atom has 32 electrons orbiting around its nucleus.

Germanium has an atomic number of 32. The mass number of any isotope is defined as the sum of the numbers of neutrons and protons in each atomic nucleus, and the number of protons is the same as the atomic number. Therefore, the number of neutrons in Ge-73 is 73 - 32 or 41.

Yes, germanium is considered brittle. It is a rigid, lustrous, and grayish-white metalloid with a crystalline structure that tends to fracture easily under stress.

No, germanium is not a halogen. It is a metalloid element that has properties of both metals and nonmetals. Halogens are a group of elements in the periodic table that includes elements like fluorine, chlorine, and iodine.

The actual density of germanium is approximately 5.323 g/cm^3 at room temperature in a reference source.

Germanium has 32 electrons and protons; the number of neutrons is specific for each isotope.

Number of neutrons in a germanium isotope = Mass number - 32
