Sulphur has the electronic configuration of 2,8,6.
It has to gain two more electrons to have a stable outer shell
. This means that sulphide ions will have two electrons more than the protons and it will have a negative charge.
How does sulfur become stable?
In order to be stable, a particle must possess an octet, or eight, fully-paired valence electrons. Sulfur would need
to gain 2 electrons
in order to achieve an octet configuration.
Is sulfur a stable atom?
It displays three allotropic forms: orthorhombic, monoclinic and amorphous.
The orthorhombic form is the most stable form of sulfur
. Monoclinic sulfur exists between the temperatures of 96°C and 119°C and reverts back to the orthorhombic form when cooled.
What is a stable electron shell?
A stable electron configuration refers
to an atom in which the outermost (valence) shell is complete
. The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled.
Does sulfur have a stable shell?
The valence shell (the 3s and 3p sublevels) contains six electrons, but
it needs eight to become stable
. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
Does sulfur need a full octet?
Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl
5
) and sulfur hexafluoride (SF
6
) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.
What is the ground state electron configuration for the most stable anion of sulfur?
Write the ground state configuration for the nonmetal sulfur, and predict the ion it must form to be isoelectronic with the nearest noble gas. Answer: The ground state configuration for the nonmetal sulfur is written as:
1s
2
2s
2
2p
6
3s
2
3p
4
. Sulfur has 16 electrons.
Why does sulfur break the octet rule?
Sulfur can make use of its 2 unpaired electrons to form 2 covalent bonds plus the 4 electrons from its 2 lone pairs to give a total of 8 electrons
. Hence sulfur obeys octet rule in this case. But sulfur can unpair its electrons and promote one of its electrons (highlighted in green) to an empty 3d orbital.
Is sulfur positive or negative?
Sulfur is in group 6 of the periodic table. What is the charge on its ions, and is the charge positive or negative?
The charge is negative
, since sulfur is a non-metal. The charge on the ion is (8 – 6) = 2.
Why does sulfur have a 2 charge?
Since electrons carry a negative charge, gaining electrons will result in the formation of a negatively charged ion, or anion. … For each electron gained, the ion’s overall charge decreases by 1 unit, which further confirms the fact that the neutral sulfur atom gained 2
electrons
to get the (2−) charge.
What is the most stable form of sulfur?
Rhombic sulphur
is the most stable allotropic form of sulphur.
What are 3 interesting facts about sulfur?
- Atomic number: 16.

What is sulfur used for today?
Today, it’s most common use is in the
manufacture of sulfuric acid
, which in turn goes into fertilizers, batteries and cleaners. It’s also used to refine oil and in processing ores. Pure sulfur has no smell. The stink associated with the element comes from many of its compounds, according to Chemicool.
Why is 3rd shell 8 or 18?
Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to
18 (2 + 6 + 10)
can hold the third shell and so on. The general formula is that the nth shell can hold up to 2(n
2
) electrons in principle.
Which noble gas does not follow the octet rule?
An exception to an octet of electrons is in the case of the first noble gas,
helium
, which only has two valence electrons. This primarily affects the element hydrogen, which forms stable compounds by achieving two valence electrons. Lithium, an alkali metal with three electrons, is also an exception to the octet rule.
Why does the octet rule exist?
The octet rule exists because
the atoms of many elements become more stable by attaining a noble gas electron configuration
. Most noble gases have eight valence electrons (He has only 2) which gives them a full outer shell of electrons in the s and p sublevels of their highest energy level.
