Sulfur is in period 3 and has 6 valence electrons. The expected fluoride would be SF2, SF^ a very stable compound is surprisoing. The bonding in SF6 has been described in a number of ways- one is that there is sp3d2 hybridisation and there are 6 equivalent 2 electron 2 center bonds. Other descriptions involve resonance of ionic canonicals where the octet is preserved. Yet another description is "hypervalency" involving 3 centre bonds.
With BeH2 the situation is different, in this there are not enough electrons to form an octet. Some call this electron deficiency. In BeH2 each Be is surrounded by 4 hydrogen atoms, and there 4 BeHBe bonds- 3 center 2 electron. These are similar to bonds in B2H6.
The octet rule is a guideline- it has proved to be remarkably useful- but as someone said ".. in inorganic chemistry the rule is that there are no rules"
What else can I help you with?
Why does nitrogen form NF3 but not SF6?
Arsenic is a metaloid with variable oxidation states. +/-3 and 5.
Would sulfur hexafluoride be classified as an ionic compound?
Sulfur hexafluoride has covalent bonds.
What is the molar mass of Na2S04?
Anhydrous sodium sulfate has a molar mass of (23+23+32+16+16+16+16) = 142.
Why dipole moment is zero in non polar molecules non zero in polar molecules?
The dipole moment is zero in nonpolar molecules and non-zero in polar molecules due to electronegativity. Polar molecules have balanced electronegativity that will cancel one another out, while nonpolar molecules have unbalanced electronegativity causing dipole moments.
Why are Gases better insulators than liquids?
hello,all gases are insulators, so if you look at the periodic table on the gas section you would realsile none are solids and none are liquids so they can definatley not be conductors. ooops i was almost going to spell condom hahahafor your information a condom is a very nice tasting rubber thing which should be put on a dick for sex :)AnswerIf the moron who provided the original answer gave some thought to the question, instead of being obsessed with condoms, he would realise that some gases are indeed conductors -otherwise fluorescent tubes and neon tubes wouldn't work, would they? But to answer the question, a gas widely used to insulate high-voltage substation equipment is SF6: sulfur hexafluoride.
What compound is the octet rule expanded to include 12 electrons?
One example of a compound where the octet rule is expanded to include 12 electrons is sulfur hexafluoride (SF6). In SF6, the sulfur atom has 12 electrons around it, exceeding the typical octet rule. This expansion allows sulfur to complete its valence shell and achieve stability.
Does SF2 obey octet rule?
No, SF6 doesn't. If you draw out the Lewis structure, all 6 fluorine atoms have to connect to the sulfur.
Can atoms combine less or more than the octet rule?
Yes. In the case of BeCl2 and BF3, there are only 4 and 6 electrons on Be and B respectively and not eight. Similarly, in the case of SF6 and PCl5, there are 12 and 10 electrons on S and P respectively and not eight.
A sulfur atom has 6 electrons in its outer shell how many covalent bonds is it likely to form with other atoms?
i dont no your level of chemistry, but if you know about orbital you will understand. sulfur is able to disobey the octect rule to form up to 6 bonds tis is due to the presence of d orbital. eg. SF6
Does AsF6- obey the octet rule?
It does not. The central arsenic atom will have 6 electron domains, which means 12 valence electrons participating in bonds with the 6 fluorine atoms. This is possible because arsenic can access the 4-d sublevel of electrons, even though it doesn't have any electrons there normally. It is therefore hypervalent.
Can some atoms exceed the limits of the octet rule in bonding?
The further down the periodic table that you go the more electrons that an element has, also the more orbitals an element has. If you look up general trends in the periodic table ionic size is showen to increase too. The ionic size is directly related to these larger orbital shells that hold more electrons. S orbital = 2 é P orbital = 6é D orbital = 10é You may want to look up these orbitals to get a better understanding of them, each one has a unique shape http://en.wikipedia.org/wiki/Atomic_orbital some atoms can exceed the octet rule by using these unfilled larger orbitals to put electrons into them, so for example they might use the D orbital to place extra electrons into it, causing the octet rule to break down.
What is the color of SF6?
Sulfur hexafluoride (SF6) is a colorless gas under normal conditions.
Is SF6 a greenhouse gas?
Yes, SF6 is a greenhouse gas.
What is the chemical name for compound SF6?
The chemical name for compound SF6 is sulfur hexafluoride.
What is the formula for monosulfur hexafluoride?
The formula for monosulfur hexafluoride is SF6.
Is SF6 a Lewis acid or base?
Sf6 acts as an lewis acid............
Where sf6 gas is filling in sf6 braker?
Usually in a sealed tank, the switch contacts are in the tank too. The SF6 gas quenches any arcs that form when the switch contacts are opened.
