Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.
To determine the number of atoms in 30.4 g of selenium, you first need to calculate the number of moles using the molar mass of selenium (78.97 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that amount of selenium. In this case, there are approximately 3.86 x 10^22 atoms in 30.4 g of selenium.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
The elemental selenium in selenium dioxide monohydrate exists as Se(IV) in the +4 oxidation state. It is bonded to two oxygen atoms in a linear configuration. The oxygen atoms are bound to the selenium atom in a double bond.
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
One atom of Se and one atom of O.

7. Selenium hexafluoride is SeF6 , an octahedral molecule similar to SF6
The oxidation states of selenium are: 1 to 6 and -1, -2.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Se4Br7 is the chemical formula for selenium tetrabromide. It is a compound composed of selenium and bromine atoms, with four selenium atoms and seven bromine atoms in each molecule. Selenium tetrabromide is a red-brown solid that is primarily used in chemical synthesis.
The elemental selenium in selenium dioxide monohydrate exists as Se(IV) in the +4 oxidation state. It is bonded to two oxygen atoms in a linear configuration. The oxygen atoms are bound to the selenium atom in a double bond.
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
One atom of Se and one atom of O.
Barium is unlikely to form a positively charged ion because it is an alkaline earth metal with a strong tendency to lose electrons and form a 2+ ion.
The binary compound SeO is selenium dioxide. It is composed of one selenium atom and two oxygen atoms. Its chemical formula is SeO2.
