Question: Can Sulfur Have More Than 8 Valence Electrons?

Why are there only 8 electrons in the outer shell?

The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons.

This is a very important rule called the Octet rule.

According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas..

Why can sulfur have more than 8 valence 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 an atom make 8 bonds?

The ability to use the d subshell is what makes it possible for atoms to go beyond the octet, and it’s also why atoms up to the second period cannot do that. For that same reason, six or seven bonds are possible, and Xenon can form 8 covalent bonds in the compound XeO4!

What does it mean if an element has 8 valence electrons?

Atoms of group 18 elements have eight valence electrons (or two in the case of helium). These elements already have a full outer energy level, so they are very stable. As a result, they rarely if ever react with other elements. … Therefore, it is very reactive and gives up electrons in chemical reactions.

Why is 3rd shell 8 or 18?

The third shell of an atom has 18 electrons only not 8 electrons. You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled. They are filled because of the n-l rule. … So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one.

Which elements can hold more than 8 valence electrons?

Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.

Why does boron only need 6 valence electrons?

Boron has a charge of 5. This is balanced by 5 electrons. … The valence electrons may participate in bonding through sharing with other atoms, to make three bonds. Three bonds = six electrons.

Why does Beryllium only need 4 electrons?

In some compounds, the number of electrons surrounding the central atom in a stable molecule is fewer than eight. Beryllium is an alkaline earth metal and so may be expected to form ionic bonds. … Since beryllium only has two valence electrons, it does not typically attain an octet through sharing of electrons.

Why can Sulfur Form 6?

Sulphur has 6 Valance electrons so according to VBT it can form maximum of 6 covalent bonds. … This is because of availablity of vacant d orbitals in Sulphur, which can accommodate extra electrons other than octet. Thus sulphur forms SF6.

Can an atom have more than 8 valence electrons?

Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.

Why does sulfur have 10 valence electrons?

Sulfur can follow the octet rule as in the molecule SF2. Each atom is surrounded by eight electrons. It is possible to excite the sulfur atom sufficiently to push valence atoms into the d orbital to allow molecules such as SF4 and SF6. The sulfur atom in SF4 has 10 valence electrons and 12 valence electrons in SF6.

How many valence electrons can Sulfur hold?

12 electronsNow sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell. So in addition to being octet, sulfur can expand octet to have 10 or 12 electrons.
