There are four principal differences between the chemistry of sulfur and oxygen. …
Sulfur (EN = 2.58) is much less electronegative than oxygen (EN = 3.44)
. 4. Sulfur can expand its valence shell to hold more than eight electrons, but oxygen cannot.
What is the relationship between oxygen and sulfur?
Sulfur is less electronegative than oxygen
(2.4 and 3.5, respectively) and as a consequence bonds to sulfur are less polar than the corresponding bonds to oxygen. One significant result in that with a less polar S-H bond the subsequent hydrogen bonding is weaker than observed with O-H analogs.
Why are oxygen and sulfur in the same group?
Sulfur forms many compounds that are analogues of Oxygen compounds. So, Oxygen and Sulphur are kept in the same group, the reason is
a similar number of electrons in the outermost shell
.

Which is more stable oxygen or sulfur?
Sulphur
is able to stabilize the negative charge more better than oxygen due to its size , But Electronegativity of Oxygen is more than Sulphur, so negative charge on oxygen should be more stable , Why it is not so ?
What is the Lewis symbol of oxygen?
The two letter
O’s
in the O2 Lewis structure represent the nuclei (centers) of the oxygen atoms. The nuclei contain the protons and neutrons, which are the solid parts of the molecule. Interestingly, the dots and lines represent electrons, which are not solid.
What do oxygen and sulfur have in common?
Oxygen Family
Each has six of the desired eight electrons required for the octet in its highest energy level. This means that it takes or accepts two electrons from atoms of other elements to form anions or shares two electrons to form covalent bonds. Oxygen and sulfur are
common elements
.
Does sulfur act like oxygen?
Because
sulfur is much less electronegative than oxygen
, it is more likely to form compounds in which it has a positive oxidation number (see table below). In theory, sulfur can react with oxygen to form either SO
2
or SO
3
, whose Lewis structures are given in the figure below.
Is sulfur more basic than oxygen?
Sulfur is a larger atom than oxygen
, making its electrons more polarizable. Thus, it is a stronger nucleophile than oxygen. However, the pka of R-SH is 8.2 where as the pka of R-OH is 16. Thus, the SH group is a stronger acid than the OH.
What happens when you burn sulfur in oxygen?
Sulfur burns in oxygen
to form sulfur dioxide
.
What is sulfur used for?
Sulfur is used in
the vulcanisation of black rubber
, as a fungicide and in black gunpowder. Most sulfur is, however, used in the production of sulfuric acid, which is perhaps the most important chemical manufactured by western civilisations.
What is Sulphur used for?
The major derivative of sulphur is sulphuric acid (H2SO4), one of the most important elements used as an industrial raw material. Sulphur is also used in batteries, detergents, fungicides,
manufacture of fertilizers, gun power, matches and fireworks
.
What happens if we burn Sulphur?
When sulfur is burned,
it turns into a gas called sulfur dioxide
. The gas can mix with moisture on plants to form an acid that can damage plant leaves. Breathing the gas can be harmful to human health.
Why sulphur is less electronegative than oxygen?
With oxygen, the bonding electrons are at the 2-level, and the 8 protons in the nucleus are shielded by the 2 electrons in the 1s orbital. … However,
the bonding electrons in the sulphur are further from the nucleus
, and so the attraction is lessened. So sulphur is less electronegative than oxygen.
Is S or O more negative?
Sulphur has
more negative electron gain enthalpy than oxygen
.
What is the common charge of sulfur?
That means that a neutral sulfur atom will need to gain two electrons to reach a full octet of eight electrons. Therefore, we predict that the most common charge on a sulfur ion will be
2-
.
