The intermolecular forces in oxygen are weak van der Waals forces, which causes it to exist as gas. On the other hand, sulphur does not form strong S=S double bonds hence exists as a puckered structure held together by strong covalent bonds and exists as a polyatomic molecule. So, it exists as a solid.

Why oxygen is O2 and sulphur is S8?

Therefore due to more number of atoms associated per molecule, sulphur exists as a solid whereas oxygen exists as a gas. ... Sulphur has a vacant D orbital so it can form Bond with other element are itself as compared to oxygen. Also O2 molecule exist where as sulphur is exist as S8 solid.

Why O2 is a gas?

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.

Why oxygen is gas while sulphur is Octaatomic solid at room temperature?

but on the other hand sulphur is larger in size than oxygen and less electronegetivity than oxygen, sulphur can't make p pi-p pi bond multiple bond. instead it prefers to form S-S single bond and as a result, sulphur exist as octaatomic (S8) and has high intermolecular force of attraction.

Why is oxygen and sulfur in the same group?

Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below.

oxygen is gas but sulphur is solid #yashsirchemistry

How is sulfur different from oxygen?

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.

Which gas is formed when sulphur reacts with oxygen?

When sulphur reacts with oxygen, sulphur dioxide forms.

Why oxygen is colorless while sulphur is Coloured?

The bleaching action of sulphur di oxide is temporary because it involves the process of reduction. sulphur di oxide removes oxygen from the coloured substance and makes it colourless.

Why sulphur is Octaatomic?

Answer:- Atomic size of sulphur is bigger. It can not form π – bond together with s – bond between S and S atoms. To satisfied its valency, it forms S8 molecule in which all atoms of sulphur bonded with only σ– bond .

Why oxygen is diatomic and gaseous in nature?

Oxygen exists as a diatomic molecule in nature when it is not combined with any other element. It forms O2 molecule because it is stable when it is uncombined. It has the lowest energy level when uncombined. Remember that stability is inversely proportional to energy.

Is O2 a gas liquid or solid?

Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule. Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O₂. Oxygen is normally found as a molecule.

Is O2 a gas?

At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2. Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time.

Is oxygen O2 or just O?

The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.

Why does O2 exist but not S2?

Oxygen is diatomic, so it exists as O2, whereas S2 is not.

Why is S8 a molecular solid?

In the ${S_8}$ molecules, the Sulphur atoms are attached to each other by weak London forces between the molecules. Also, it does not conduct electricity because of the lack of free electrons. So, ${S_8}$ molecules are the molecular solids.

Is S8 a solid liquid or gas?

Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S₈. Elemental sulfur is a bright yellow, crystalline solid at room temperature.

Why is oxygen a stable molecule?

So, for the oxygen atom to be stable it requires two more electrons in the valence shell. The oxygen atom forms a covalent bond with another atom of oxygen and shares 2 electrons in order to make the valence shell electrons to be equal to 8. An oxygen molecule(O₂) with two atoms of oxygen is stable.

Why oxygen does not exist as o8?

Oxygen does not have strong Vander Wall forces among atoms and so it exists as a gas at room temperature. It forms Pπ bonds. ... So it forms a solid structure at room temperature. However, it forms Pπ-Pπ bonds but not so stable as oxygen.

Why is oxygen a diatomic molecule?

Oxygen generally exists as a diatomic molecule in the atmosphere when it is not combined with any other element. ... In the standard model of the oxygen molecule, each oxygen atom shares two pairs of electrons. thus each atom can be considered to have at some time 8 electrons in its valence shell.

How does sulphur react with oxygen?

Sulfur reacts with oxygen to form sulfur dioxide. When nonmetals react with one another, the product is a molecular compound. Often, the nonmetal reactants can combine in different ratios and produce different products. Sulfur can also combine with oxygen to produce sulfur trioxide.

Why is oxygen diatomic but not sulfur?

Why oxygen molecule is diatomic whereas sulphur molecules is octa atomic? Oxygen atom is small and hence capable of forming pπ-pπ multiple bond and thus exists as O2. On the other hand, due to large size, sulphur does not form pπ-pπ multiple bond and form S8 rings.

Is sulfur and oxygen ionic or covalent?

Sulfur and oxygen are both nonmetals due to their position on the periodic table, and so sulfur monoxide or SO would just be held by covalent bonding.

When sulphur solid reacts with oxygen gas the product formed is sulphur dioxide the physical state of sulphur dioxide is?

Since here sulphur exists in solid form and oxygen and sulphur dioxide exist in gaseous form. Sulphur dioxide is liquefied at room temperature at 2 atmospheric pressure and having acidic nature and non-supporter of combustion.

When sulphur reacts with oxygen the oxide formed is which nature?

When Sulphur burns in the presence of oxygen , it reacts with oxygen and forms a Sulphur dioxide Which is Acidic in Nature. Capture the Sulphur di oxide gas in a bottle and mix that gas with water.

What is the action of O2 on SO2?

2SO2 + O2 → 2SO3.
