Why does sulfur have a valency of 4 and 6 when it needs only 2 electrons for stable configuration?

It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.

How do you identify valency of any atom?
The easiest way to determine the valency of an atom is to locate its place on the periodic table. Generally, it is useful to remember that metals tend to give away valence electrons where non metal atoms tend to obtain them. For example, sodium, a metal, is in group 1 has valency of 1. Sulfur, a non metal, is in group 16 and is 2 electrons away from its stable electron configuration, hence it has valency of 2.
What is the electron configuration of a element of 16 electrons?
The electron configuration of sulfur is [Ne) 3s2.3p4.
Which element will have a noble gas configuration if it forms an ionic bond by accepting two electrons from a magnesium atom?
sulfur
When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
How many electrons does sulfur gain to attain a noble gas configuration?
Gain two electrons to have the electron configuration as Argon

How many electrons does sulfur gain or lose to become stable?
Sulfur gains 2 electrons to become stable.
What is the Valency of sulfur?
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
Why valency of sulfur is 2 4 and 6?
Actually it is about the orbitals of valence shells of sulphur. Sulphur has atomic no. 16 and electronic configuration 1s2,2s2,2p6,3s2,3p4. Its outer most shell has s.p.d and f orbitals from which s and p have electrons and d and f are vacant. When 2 electrons from p are transferred to d, the valency becomes +2. When two more electrons from p are transfered to d, the valency becomes +4. When two left electrons from s are transferred to d, the valency becomes +6.
How many electrons dose Sulfur need to gain in order to have the same electron configuration as Argon?
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
What is the electron configuration of a element of 16 electrons?
The electron configuration of sulfur is [Ne) 3s2.3p4.
Is sulfur outer most shell stable?
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.
What is the valency of sulfur in sulfuric acid?
+6 valency
How many electrons does sulfur need to be a stable octet?
only 2
Which element has the electron configuration Ne3s23p4?
Silicon.Neon has 10 electrons. Adding 4 more electrons to that gives 14 electrons, and the configuration of [Ne] 3s2 3p2. This configuration belongs to the element silicon.
What is the valency of sulphur in ammonium sulphate?
The valency of sulfur is 2.
How many valence electrons does Sulfur?
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.
