What is the oxidation state for selenium?
The 4 natural oxidation states of selenium are elemental selenium (0), selenide (-2), selenite (+4), and selenate (+6).
What is the most common oxidation state of selenium?
In compounds of selenium (where known), the most common oxidation numbers of selenium are: 6, 4, 2, and -2.
What is the group number of selenium?
Group 16
selenium (Se), a chemical element in the oxygen group (Group 16 [VIa] of the periodic table), closely allied in chemical and physical properties with the elements sulfur and tellurium. Selenium is rare, composing approximately 90 parts per billion of the crust of Earth.
What is the mass number for selenium?
78.96 u
Selenium/Atomic mass
What is se in organic chemistry?
Organoselenium compounds (or seleno-organic) are chemical compounds containing carbon-to-selenium chemical bonds. Selenium can exist with oxidation state −2, +2, +4, +6. Se(II) is the dominant form in organoselenium chemistry.
What is the oxidation number of superoxide?
-1/2
The oxidation number of oxygen in superoxides is -1/2 i.e. O-1/2.
Is Selenium A se2?
Selenium is a chemical element with the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic.
What is the charge of a selenium?
0
Elemental Se has a charge of 0.
What is the oxidation number of selenium SE in SeO2 − 4?
+4
As the compound SeO2 S e O 2 is neutral, the total charge of the compound is taken as zero. Thus, the oxidation number of selenium is +4, and that of oxygen is -2 respectively.
What ion is se2?
selenide ion
A selenide is a chemical compound containing a selenium anion with oxidation number of −2 (Se2−), much as sulfur does in a sulfide. The chemistry of the selenides and sulfides is similar. Similar to sulfide, in aqueous solution, the selenide ion, Se2−, is prevalent only in very basic conditions.
What are the possible oxidation states of selenium?
Electron Configuration and Oxidation States of Selenium. Electron configuration of Selenium is [Ar] 3d10 4s2 4p4. Possible oxidation states are +4,6/-2. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties.
