Is germanium oxide covalent or ionic?
Answer: Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2.
Is NaCl a covalent compound?
Covalent Bonding. Ionic compounds, such as sodium chloride (NaCl), are formed by a transfer of electrons that creates ions. The hydrogen and oxygen atoms in a water molecule, however, are bonded by sharing electrons rather than by transferring them.
Which type of oxide is germanium oxide?
Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium….Germanium dioxide.

Is germanium dioxide amphoteric?
GeO is not well characterised. It is amphoteric dissolving in acids to form germanium(II) salts and in alkali to form “trihydroxogermanates” or “germanites” containing the Ge(OH)3− ion….Germanium monoxide.

Is rb2se an ionic compound?
Here it is a metal, and it has a plus one charge. And again, guys, ionic compounds are formed when we combine a metal with a non metal right, so we know that it’s an ionic compound.
Is NaCl polar covalent or ionic?
Sodium Chloride (NaCl) which is an ionic compound acts as a polar molecule. Usually, the large difference in electronegativities in sodium and chlorine makes their bond polar.
Is NaCl ionic compound?
Sodium chloride
Sodium chloride/IUPAC ID
What is germanium metal or nonmetal?
Germanium itself is classified as a metalloid. It’s hard at room temperature and looks metallic with a shiny silvery grey finish, but it’s a semiconductor, without some of the key properties of a metal.
What is a covalent bond and what is an ionic bond?
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. A covalent bond involves a pair of electrons being shared between atoms. Atoms form covalent bonds in order to reach a more stable state.
How do you identify an ionic compound?
To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.
Which oxide of germanium is amphoteric?
The yellow sublimate turns brown on heating at 650 °C. GeO is not well characterised. It is amphoteric dissolving in acids to form germanium(II) salts and in alkali to form “trihydroxogermanates” or “germanites” containing the Ge(OH)3− ion….Germanium monoxide.

How is germanium tetrachloride produced from Geo 2?
Germanium tetrachloride is an intermediate for the purification of germanium metal or its oxide, GeO 2. Germanium tetrachloride can be generated directly from GeO 2 ( germanium dioxide) by dissolution of the oxide in concentrated hydrochloric acid.
Why are only two atoms surrounding the central germanium atom?
Germanium chloride has only two atoms surrounding the central germanium atom. Why then is the germanium chloride molecule bent? A lone pair of electrons on germanium pushes it to this orientation.
Where does most of the germanium in the world come from?
Most commercial production of germanium is from treating flue-dusts of zinc- and copper-ore smelters, although a significant source is also found in the ash from the combustion of certain types of coal called vitrain. Germanium tetrachloride is an intermediate for the purification of germanium metal or its oxide, GeO 2.
How is the index of refraction of germanium tetrachloride controlled?
The GeO 2 has a high index of refraction, so by varying the flow rate of germanium tetrachloride the overall index of refraction of the optical fiber can be specifically controlled. The GeO 2 is about 4% by weight of the glass.
