542 Questions

How many covalent bonds does germanium form in chemistry?

Germanium typically forms four covalent bonds in chemistry. It has four valence electrons, so it tends to share these electrons with other atoms to complete its octet structure.

What is a germanium's atomic number How many electrons does germanium have?

Germanium Atomic number is 32 and the number of electrons is 32

What is the atomic weight of germanium?

Germanium (Ge) has an atomic weight of 72.64 g/mol

How many core electrons are in germanium?

In germanium, the number of core electrons is equal to the number of electrons in its inner shells. The electron configuration of germanium is [Ar] 3d10 4s2 4p2, where [Ar] represents the electron configuration of argon. Therefore, germanium has 18 core electrons.

Why germanium is diamagnetic?

Germanium is diamagnetic because it has all of its electron spins paired, resulting in no net magnetic moment. This means that germanium does not exhibit magnetic properties in the presence of an external magnetic field, unlike paramagnetic or ferromagnetic materials.

How much does germanium cost for one ounce?

The cost of germanium varies depending on the purity level, market conditions, and supplier. As of now, the price of germanium is roughly $2,000 to $3,000 per ounce.

What is the orbital diagram for germanium?

The orbital diagram for germanium (Ge) shows its electron configuration as [Ar] 3d10 4s2 4p2. This means that germanium has 2 electrons in its 4p orbital, 2 electrons in its 4s orbital, and 10 electrons in its 3d orbital.

What temperature is germanium?

Usually the same temperature as the things around it. Most materials tend to be at the same temperature as the things around them.

Where is germanium used most?

Germanium is primarily used in the production of semiconductors for electronic devices such as transistors and diodes. It is also used in infrared optics, fiber optics, and as a catalyst in polymerization reactions.

What is germanium reactivity?

Germanium is a metalloid with low reactivity. It is relatively stable in air and water, but can react with strong oxidizing agents. Germanium primarily forms covalent bonds rather than ionic bonds due to its electron configuration.

What would you multiply atoms of germanium by to get the units moles of germanium?

The conversion factor you need for this problem is Avogadro's number.

(6.02 x 1023 atoms germanium/1 mole germanium) = 1

... OR ...

(1 mole germanium/6.02 x 1023 atoms germanium) = 1

Since you want to end up in units of moles of Ge, this goes in the numerator (on top). You want to convert from atoms Ge, so this goes in the denominator (on the bottom).

atoms Ge1 mole Ge = moles Ge6.02E+23 atoms Ge

What would you multiply grams of germanium by to get the units moles of germanium?

The conversion factor you need for this problem is the atomic mass of germanium.

72.6 gram germanium = 1 mole germanium

Since you want to end up in units of moles of Ge, this goes in the numerator (on top). You want to convert from grams Ge, so this goes in the denominator (on the bottom).

grams Ge1 mole Ge = moles Ge72.6 gram Ge

How many bonds and lone pairs are with germanium?

Germanium typically forms four covalent bonds and has no lone pairs in its ground state.

Does germanium react with water?

They dont love each other so much.

Actually Ge is readily oxidized to GeO2 by Oxygen.

GeO2,not Ge ,dissolves into water 4.5gram in 1000 gram water.

What is the ionic charge for germanium?

Germanium is in the fourth period of the periodic table. It exhibits two oxidation states GeII and GeIV

This tendency for a lower oxidation state is termed the "inert pair effect".

Looking at the halides GeF2 is a volatile white solid with an unusual structure which does not suggest that the bonding is ionic.

GeCl4 is a covalent molecular compound like CCl4 and SiCl4

the oxides GeO2 and GeO are both known but GeO is unstable disproportionates to GeO2 and metallic germanium. In the oxides the bonding but like silicon oxides, it is best described as covalent.

So in summary Ge2+ and Ge4+ (and these will probably be present in mass spectrometer beams) with the proviso that ions with a 4+ charge in reality are so strongly polarising that they will form bonds with a degree of covalency.

Why are germanium and silicon similar to each other?

Germanium and silicon are both metalloids in the same group of the periodic table, sharing similar chemical properties. They are both commonly used in electronics as semiconductor materials due to their ability to conduct electricity under certain conditions. Additionally, germanium and silicon have similar crystal structures, making them suitable for producing similar types of electronic components.

How did Mendeleev predict germanium?

Mendeleev predicted the existence and properties of germanium by leaving gaps in his periodic table for elements that had not yet been discovered. He correctly deduced the properties of the missing element based on the pattern of elements around its position in the table. When germanium was discovered, its properties closely matched Mendeleev's predictions, confirming the validity of his periodic table.

What is the oxidation state of germanium in germanium tetrachloride?

The oxidation state of germanium in germanium tetrachloride (GeCl4) is +4. This is because each chlorine atom has an oxidation state of -1, and since there are four chlorine atoms in GeCl4, the oxidation state of germanium must be +4 to balance the overall charge of the compound.

Why are silicon and germanium considered to be semiconductors?

Silicon and germanium are considered semiconductors because they have a conductivity between that of a conductor and an insulator. They have a crystalline structure which allows them to conduct electricity when impurities are added or when exposed to heat or light. This property makes them valuable materials for creating electronic devices like transistors and diodes.

What atom is smaller tin or germanium?

Germanium atoms are smaller than tin atoms because germanium has a higher atomic number and more protons in the nucleus. The increased positive charge from more protons attracts the negatively charged electrons more strongly, leading to a smaller atomic size.
