It is a covalent bond.
Selenium (II) chloride.
The common name is selenium fluoride. In this molecule, the Se atom is in +2 oxidation state. Therefore the corresponding IUPAC name is Selenium(II) Chloride.
Selenium Monoiodide
Selenium dioxide has a bent molecule.
Hydrogen, Oxygen, Chlorine, Fluorine, Iodine, Bromine, Tellurium, Selenium, Sulphur, Nitrogen, etc.
B. moderately polar covalent
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.
Selenium (II) chloride.
A sulfur atom is larger than an oxygen atom.
The common name is selenium fluoride. In this molecule, the Se atom is in +2 oxidation state. Therefore the corresponding IUPAC name is Selenium(II) Chloride.
chlorine is more reactive than selenium. Chlorine needs one electron to form octet whereas selenium needs two.
SeI4
Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
Selenium dioxide has a covalent or molecular bond.
7. Selenium hexafluoride is SeF6 , an octahedral molecule similar to SF6
1. As a metal gold has metallic bonds. 2. Gold can react with sulfur, selenium, chlorine etc.
Selenium Monoiodide
