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.
How many electrons does sulfur gain to attain a noble gas configuration?
Sulfur gains two electrons to attain a noble gas configuration, which is the electron configuration of argon. This allows sulfur to have a stable octet of electrons in its outer shell and achieve a more stable electron configuration.
What is the electron configuration of a element of 16 electrons?
The electron configuration of sulfur is [Ne) 3s2.3p4.
What is the cation S2?
The cation S2- is called sulfide ion. It has a charge of -2 and is formed when sulfur gains two electrons to achieve a stable electron configuration.
Electron configuration of Core Electrons of Sulfur?
The core electron configuration of sulfur is [Ne] 3s^2 3p^4, where [Ne] represents the electron configuration of the noble gas neon. This indicates that sulfur has a full 3s subshell and 4 electrons in the 3p subshell within its core electron configuration.
Why sulphur exhibit negative valency?
Sulfur can exhibit a negative valency because it can gain electrons to achieve a stable electron configuration, typically by forming sulfide ions (S2-). This allows sulfur to reach a more stable octet electron configuration, as it gains two electrons to have a full valence shell.
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.
Why is valency of sulfur -2?
Because of its position on the periodic table (determined by the number of protons in the nucleus) it has 6 valence electrons. A stable Octet would give it an Argon structure. So it wants to gain 2 electrons rather than lose 6 as gaining 2 is more energetically favorable. So if it gained 2 it would have a -2 charge - hence the valency is often stated as -2.
How many electrons does sulfur need to be a stable octet?
Sulfur needs 2 more electrons to achieve a stable octet, making a total of 8 electrons in its outer shell to achieve a stable electron configuration.
How many electrons do sulfur gain?
Sulfur can gain 2 electrons to achieve a stable electron configuration, reaching a full octet in its outer shell. The most common oxidation state of sulfur is -2, where it gains 2 electrons to become stable.
How many electrons will sulfur gain or lose What will its charge be?
Sulfur, with its 6 valence electrons, will gain 2 electrons to achieve a stable octet configuration, resulting in a charge of -2.
When sulfur reacts with other elements it does not lose its electrons but rather gain two electrons why?
Sulfur has six valence electrons in its outer shell. When it reacts with other elements, it tends to gain two electrons to achieve a stable electron configuration with a full outer shell of eight electrons, similar to the noble gas configuration. This allows sulfur to form stable compounds by achieving a more stable electron arrangement.

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 sulfur of outer electrons?
Sulfur has 6 outer shell electrons, which are located in the third energy level. These electrons are involved in forming chemical bonds with other atoms to complete sulfur's outer shell and achieve a stable electron configuration.
How many valence electrons are in a sulfur atom and a sulfide ion?
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
What is the charge of sulfur anion?
The charge of a sulfur anion is typically 2-. It gains two electrons to achieve a stable electron configuration similar to that of a noble gas.
Does sulfur for ionic or covalent bonds?
Sulfur can form both ionic and covalent bonds. In ionic bonds, sulfur tends to gain two electrons to achieve a stable octet configuration. In covalent bonds, sulfur often shares electrons with other nonmetals.
