sp3d. For each energy level (s,p,d,f) there are a certain amount of atoms in that section. S has 2. Divide it by two, you get one. P has 6. Divide it by 2, you get 3, and so on. Because selenium tetrafluoride has 5 things around it (four fluorides and a lone pair), it will go up to 5, which is sp3d.
trigonal bipyramidal
Selenium tetrafluoride is SeF4
Tetraflouride is not a substance in its own right, it merely means that something has 4 fluorine atoms in a molecule. Such a formula will end in F4, but it must be preceded by something. Examples: Carbon tetrafluoride is CF4, silicon tetrafluoride is SiF4, and diboron tetrafluoride is B2F4.
Jons Jacob was the man to discover Selenium.
CFC. Its used as an abbreviation for elements that effect the ozone layer.
The chemical name of Tetrafluorohydrazine has the molecular formula N2F4. Tetrafluorohydrazine is a toxic organic compound with a molecular weight of 104.0 grams per mole.
Selenium tetrafluoride is SeF4
Selenium Tetrafluoride
The Se (selenium) would be sp3d hybridized.
sp3d is a typical answer - bit this assumes that d orbitals are sigificant in the bonding- you may be being taught differently.
The silicon tetrafluoride formula is SiF4.
The Correct Chemical Name is: xenon tetrafluoride
The chemical formula for sulfur tetrafluoride is SF4.
It could be named any one of monosilicon tetrafluoride, silicon tetrafluoride, or tetrafluorosilane.
Tetraflouride is not a substance in its own right, it merely means that something has 4 fluorine atoms in a molecule. Such a formula will end in F4, but it must be preceded by something. Examples: Carbon tetrafluoride is CF4, silicon tetrafluoride is SiF4, and diboron tetrafluoride is B2F4.
See the link below for a MSDS of uranium tetrafluoride. Uranium tetrafluoride is dangerous: radioactive, toxic, corrosive; can affect eyes, skin and lungs (after inhalation).
The hybridization of PH3 is sp3
Disulfer tetrafluoride is S2F4.S = SulfurF = FluorineIts molecular weight is 140.1236 g/mol.
