Germanium

The most common isotope of Germanium has 40 neutrons.

Which is the pentavalent impurity is boron or germanium or indium or antimony

Germanium has 32 protons, so for an isotope with atomic number of 70, it will have 70 - 32 = 38 neutrons in its nucleus.

Germanium belongs to the fourth period of the periodic table.

Germanium belongs to group 14 (IVA) of the periodic table which is also known as the carbon group. This group includes elements such as carbon, silicon, tin, and lead. Germanium shares similar chemical properties with these elements.

The melting point of germanium is 938.25°C.

Germanium can form compounds with elements such as oxygen, sulfur, and chlorine. For example, germanium dioxide (GeO2) and germanium tetrachloride (GeCl4) are common compounds formed by combining germanium with oxygen and chlorine, respectively.

The price of Germanium can vary, but on average it costs around $1-2 per gram. The price can fluctuate based on demand, availability, and purity of the element.

Germanium has 32 protons.

Germanium is a metalloid with a melting point of 938.25 degrees Celsius. However, it has a very low boiling point at 2833 degrees Celsius.

Germanium is in group 14 which in increasing atomic number are carbon, silicon, germanium, tin and lead

The silicon diode (unless its a Schottky diode) conducts at approximately 0.6 volts. The germanium diode, however, conducts at a much lower voltage, typically 0.2 volts. This means that the germanium diode is better at small signal rectification applications, such as AM radio detectors, allowing a smaller tuner tank circuit.

Germanium is primarily obtained as a byproduct of zinc ore processing. It can also be found in some coal deposits. Germanium can be further extracted through a process called zone refining or by recycling electronic waste.

Germanium is a solid and neither liquid nor gas.

To find the mass of 10 moles of germanium, you need to multiply the molar mass of germanium by the number of moles. The molar mass of germanium (Ge) is approximately 72.63 g/mol. Therefore, the mass of 10 moles of germanium would be 726.3 grams.

Germanium has thirty two protons. If two were removed, the atom would have thirty protons, making it Zinc.

If you remove two protons from a germanium atom, it would become a selenium atom. This is because germanium has 32 protons, while selenium has 34 protons.

In 1886 a German chemist named, Clemens A. Winkler discovered germanium. He discovered the first trace of germanium in the mineral argyrodite, while isolating it. (But germanium rarely makes distinct minerals.) He purified it to find the new element. Before this in 1871 a chemist named, Mendeleev predicted there would be a new element, that would have properties similar to the ones in silicon. His predictions were proved to be true.

Germanium is chemically similar to silicon because they are both metalloids belonging to Group 14 of the periodic table. They have similar atomic structures with four valence electrons, allowing them to form covalent bonds in a similar manner. This results in similar chemical properties such as the ability to form tetrahedral structures and exhibit semiconductor behavior.

Germanium at room temperature is in the state of a Solid

No, germanium is a semiconductor material, not an insulator. It has electrical properties that are in between conductors (like metals) and insulators (like nonmetals), making it useful for various electronic applications.

== When we make a semiconductor junction (a p-n junction), the electric fields force charges to shift creating what is called a depletion region. This depletion region forms a potential barrier across the junction. This potential barrier has a voltage associated with it, and that voltage is 0.3 volts (approximately) for germanium semiconductor material, and 0.7 volts (approximately) for silicon semiconductor. The terms we apply to this barrier potential are the built-in voltage (or potential), junction voltage (or potential), and contact potential.

no, it is very brittle

Germanium and fluorine will form an ionic bond, as germanium is a metalloid and fluorine is a non-metal. Germanium will donate electrons to fluorine to complete its outer electron shell, creating a stable ionic compound.
