How are some atoms able to have more than an octet and create a Hypervalent molecule?
A hypervalent molecule is a molecule that contains one or more main group elements that bear more than eight electrons in their valence levels as a result of bonding. Therefore, the d orbitals participate in bonding with other atoms and an expanded octet is produced.
Can you have more than 8 valence electrons?
Unlike atoms from periods one and two that only have the s and p orbitals (total of 8 valence electrons), atoms like phosphorus, sulfur, and chlorine can have more than 8 electrons because they are not restricted to the s and p orbitals and have a d orbital for additional electrons needed for bonding.
Why is 8 The maximum number of valence electrons?
Why is 8 the maximum number of valence electrons? – Quora. 8 is the maximum only for p block elements like chlorine, oxygen. These elements have both the s orbital and as well as the p orbital which takes part in bonding. And they can contain a maximum of 8 electrons only.
Why can sulfur have more than 8 electrons?
To accommodate more than eight electrons, sulfur must be using not only the ns and np valence orbitals but additional orbitals as well. Sulfur has an [Ne]3s23p43d0 electron configuration, so in principle it could accommodate more than eight valence electrons by using one or more d orbitals.
Can nitrogen have more than 8 valence electrons?
The total number of valence electrons is 5+6=11. Therefore, no matter how electrons are shared between the nitrogen and oxygen atoms, there is no way for nitrogen to have an octet.
Which atoms can have less than 8 valence electrons?
Hydrogen, beryllium, and boron have too few electrons to form an octet. Hydrogen has only one valence electron and only one place to form a bond with another atom. Beryllium has only two valence atoms, and can form only electron pair bonds in two locations.
Is there a limit to the number of valence electrons explain?
Since S cannot reach into its d-orbitals, it cannot have more than 8 electrons in its valence (see other discussions on this page for definitions of valence etc, but by the most basic definition, yes, only 8).
What are hypervalent molecules give an example?
Hypervalent molecule. A hypervalent molecule is a molecule that contains one or more typical elements (group 1, 2, 13-18) formally bearing more than eight electrons in their valence shells. Phosphorus pentachloride (PCl 5), sulfur hexafluoride (SF 6), the phosphate (PO 4 3−) ion, and the triiodide (I 3 −) ion are examples of hypervalent molecules.
Is the octet rule applicable to hypervalent molecules?
As another description of hypervalent molecules, modifications of the octet rule have been attempted to involve ionic characteristics in hypervalent bonding. As one of these modifications, in 1951, the concept of the 3-center-4-electron (3c-4e) bond, which described hypervalent bonding with a qualitative molecular orbital, was proposed.
Are hypervalent hydrides electronegative?
Most known hypervalent molecules contain substituents more electronegative than their central atoms. Hypervalent hydrides are of special interest because hydrogen is usually less electronegative than the central atom. A number of computational studies have been performed on chalcogen hydrides and pnictogen hydrides.
Are hypervalent compounds more stable than other compounds?
Hypervalent compounds are very common and in general are no less stable than compounds that conform to the octet rule.
