What does selenium and oxygen combined together make?
Selenium dioxide, SeO2
Is selenium stable or unstable?
Selenium is generally considered stable in its elemental form. However, some of its isotopes are unstable and undergo radioactive decay.
Is selenium a mixture?
No, selenium is a chemical element found on the periodic table with the atomic number 34 and symbol Se. It is a non-metal element that can exist in various forms, such as pure elemental selenium or in compounds with other elements.
Is selenium-dioxide is more acidic then sulfur-dioxide?
Selenium is considered a heavy metal (although ironically a non-metal) and when combined with oxygen has relatively weak intramolecular forces that are easily overcome by the strong polarity of water forcing it to ionise. Sulfur ionises less readily
What is the composition and structure of selenium?
Selenium is a nonmetal element that belongs to the oxygen group of the periodic table. Its atomic number is 34, and it has multiple allotropes with different physical and chemical properties. Selenium exists in various forms, including elemental selenium, selenide ions, selenite ions, and selenate ions.
What is Name of the covalent compound SeO2?
The name of the covalent compound SeO2 is selenium dioxide.
How do toxic is selenium?
Elemental selenium is nontoxic, hydrogen selenide and other selenium compounds are extremely toxic and resemble arsenic in their physiological reactions.
What is the binary compound SeO?
The binary compound SeO is selenium dioxide. It is composed of one selenium atom and two oxygen atoms. Its chemical formula is SeO2.

What is the Oxidation number of Se8?
Zero. Se8 is th elemental form of selenium and oxidation numbers are not applied to elemental forms. Se8 is a ring and each selenium is bound to two others.

What are five compounds of selenium?
Selenium dioxide: SeO2 Potassium selenate: K2SeO4 Selenium tetrabromide: SeBr4 Selenous acid: H2SeO3 Selenium disulphide: SeS2 Selenium hexafluoride: SeF6 Potassium selenocyanate: KSeCN
Is selenium-dioxide is more acidic then sulfur-dioxide?
Selenium is considered a heavy metal (although ironically a non-metal) and when combined with oxygen has relatively weak intramolecular forces that are easily overcome by the strong polarity of water forcing it to ionise. Sulfur ionises less readily
Does selenium blow up with chlorine?
It doesn't seem likely. Selenium isn't terribly reactive, and selenium monochloride exists in equilibrium with a different kind of selenium chloride, chlorine gas, and elemental selenium; this indicates that there's not a huge energy difference between the uncombined elements and the compound, as you would expect there to be if they "blew up" when combined.
Is carbon dioxide part of sulfur tellurium selenium or polonium?
Carbon dioxide is not part of sulfur, tellurium, selenium, or polonium. Carbon dioxide is a compound composed of carbon and oxygen atoms. Sulfur, tellurium, selenium, and polonium are elements on the periodic table that do not contain carbon or oxygen in their chemical structures.
