What is the formula for germanium disulfide?
GeS2Germanium(IV) Sulfide / Formula
How many single bonds are found in the Lewis structure of germanium disulfide?
Chemical Structure Description The GERMANIUM DISULFIDE molecule contains a total of 2 bond(s) There are 2 non-H bond(s), 2 multiple bond(s) and 2 double bond(s).
Is germanium a metal?
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.

The oxidation number of germanium in germanium disulphide is 4.
What are the bond angles for germanium disulfide?
Every germanium atom is tetrahedrally linked to four sulphur atoms, with an interatomic distance of 2.19A. The angle between the two sulphur bonds is 103°.
How do you know if a compound is covalent?
Classifying compounds as ionic or covalent
- If a compound is made from a metal and a non-metal, its bonding will be ionic.
- If a compound is made from two non-metals, its bonding will be covalent.
Is germanium toxic to humans?
Germanium is not an essential element. Its acute toxicity is low. However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death. Signs of kidney dysfunction, kidney tubular degeneration, and germanium accumulation were observed.
Is germanium safe to touch?
Route of Entry: Skin Contact Skin Absorption Eye Contact Inhalation Ingestion Germanium metal is relatively non-toxic by all routes of exposure, particularly in massive forms.
Is zirconium toxic to humans?
Toxicity Most zirconium compounds have low systemic toxicity due to their poor solubility. However, some soluble compounds, such as zirconium tetrachloride, are irritants and may cause corrosive injury. In addition, skin and lung granulomas have been reported following repeated zirconium exposure.
What is the oxidation number for ges2?
What is the shape of geo2?
Structure. The two predominant polymorphs of GeO2 are hexagonal and tetragonal. Hexagonal GeO2 has the same structure as β-quartz, with germanium having coordination number 4.
Between which types of elements do ionic bonds occur and how do electrons act within the bond?
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons….Table 2.11.

What does germanium do to the body?
Inorganic (elemental) germanium is LIKELY UNSAFE. This includes certain compounds such as germanium oxide. There have been more than 30 reports of kidney failure and death linked with use of these forms of germanium. It builds up in the body and can damage vital organs such as the kidneys.
