Why oxygen is a gas while sulphur is a solid explain?
Oxygen is smaller in size compared to sulphur. Oxygen exists as (O=O) with weak intermolecular forces of attraction whereas Sulphur exists in puckered structure, octatomic (S8) forming S-S bond with strong forces if attraction. Hence Oxygen exists as gases whereas Sulphur exists as solid.
Why does oxygen exist as a gas at room temperature?
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.
Does sulfur exist as a gas at room temperature?
Sulfur is a chemical element with symbol S and atomic number 16. Classified as a nonmetal, Sulfur is a solid at room temperature.
Why oxygen is O2 and sulphur is S8?
Atomic size of oxygen is smaller. It can form σ– bond as well as π– bond between O and O atoms and exists as O2. To satisfied its valency it forms S8 molecule in which all atoms of sulphur bonded with only σ– bond .
Why oxygen is diatomic while sulphur is Octaatomic?
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.
Why oxygen exist as O2 and sulphur as S8?
Oxygen molecule has the formula O_(2) while sulphur is S_(8). In the molecule of oxygen, the two oxygen atoms are linked to each other by double bond (O=O) i.e., one sigma bond formed by axial overlap and one pi-bond formed as a result of sidewise overlap. Therefore, oxygen exists as a diatomic molecule.
Can sulfur be a gas?
Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum….
| Sulfur | |
|---|---|
| Phase at STP | solid |
| Melting point | 388.36 K (115.21 °C, 239.38 °F) |
| Boiling point | 717.8 K (444.6 °C, 832.3 °F) |
Does sulfur exist as a liquid?
Just above its melting point, sulfur is a yellow, transparent, mobile liquid.
Why sulphur exists as S8?
Sulphur form 8 atom molecule because S-S double bond is weak due to it’s large atomic size so it form single bond in it’s elemental form. So sulphur form 2 single bond with 2 different sulphur and it form a octet ring .
Why does oxygen exist O2?
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 oxygen exists as O2 while sulphur exists as S8?
Why oxygen exists as O2 and sulphur exists as S8?
Atomic size of oxygen is smaller. It can form σ– bond as well as π– bond between O and O atoms and exists as O2. 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 .
