B. moderately polar covalent
slicon of course
iron, copper, zinc, magnesium, selenium, iodine, chlorine, chromium, cobalt, etc.
Sulfur is in group 16. Other members are oxygen, selenium, tellurium and polonium and in some respects their chemistry is similar. The elemnt most like sulfur is selenium and to a lesser extent tellurium. Polonium is a metal, and oxygen has a high electronegativity which has a major effect on the chemistry
Sulfur hexachloride is an inorganic compound consisting of two different elements. The prefix hexa indicates that there are six chloride atoms. Thus, the formula is SCl6. Note that this compound does not obey the octet rule.
The minerals beneficial to the human body are: sodium potassium chloride calcium phosphate sulfate magnesium iron copper zinc manganese iodine selenium molybdenum
It is a covalent bond.
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 dioxide has a covalent or molecular bond.
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.
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
