Why does sulfur have higher melting point than oxygen?

That’s the bare bones answer to your question. Because the intermolecular forces in sulfur are much stronger than those in oxygen, it takes more energy to melt sulfur than it does to melt oxygen.

What are the differences between oxygen and sulphur?

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 does sulfur have a lower melting point?

Phosphorus, sulfur, chlorine and argon These elements are non-metals. The melting and boiling points of these elements are very low because: van der Waals’ forces are very weak forces of attraction … little energy is needed to overcome them.

Why does sulfur have a high melting point?

Sulfur: sulfur consists of S8 rings of atoms. The molecules are bigger than phosphorus molecules, and so the van der Waals attractions will be stronger, leading to a higher melting and boiling point.

Does sulfur or oxygen have higher melting point?

Therefore it has weak temporary dipoles. Hence sulphur having strong forces of attraction will have higher melting and boiling points compared to oxygen.

Why is oxygen similar to sulfur?

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.

Why are sulphur and oxygen 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.

What is the melting point of Sulphur?

235°F (112.8°C)
Sulfur/Melting point

Why sulfur has a higher melting point than chlorine?

Sulphur has the highest melting point as it exists as S8 molecules. These molecules are quite large, so the number of electrons in the molecule is high and the Van der Waal’s forces are quite strong.

Why Sulfur has a higher melting point than chlorine?

Why is the boiling point of sulfur higher than the boiling point of oxygen?

A molecule of sulphur is made of Packard ring of eight atoms joined together by strong covalent bonds while a molecule of oxygen has weak van der waal forces between the molecules hence higher boiling point in sulphur than oxygen.

What is the difference between the melting point of oxygen and sulphur?

Account for the following : There is large difference between the melting and boiling points of oxygen and sulphur. The oxygen exists as a diatomic molecule, O 2, while sulphur exists as a polyatomic molecule, S 8. Hence, there is a large difference between the melting point and the boiling point of oxygen and sulphur.

Why does oxygen exist in solid state but sulfur does not?

Oxygen is gas due to which the molecules are loosely bonded due to which less energy (heat) is required to break the molecules. Sulfur exist in solid state as a non-metal since it is solid the molecules are tightly bonded therefore high amount of energy (heat) is required to break the molecules.

Why are oxides of sulfur called oxides?

These compounds are called oxides of sulfur since they are formed from the reaction between sulfur and O 2 molecules. The main difference between SO 2 and SO 3 is that SO2 has two oxygen atoms bonded to a sulfur atom whereas SO3 has three oxygen atoms bonded to a sulfur atom.

Why is sulfur a gas at room temperature?

Now, the fact that oxygen is a gas at room temperature means that, not only has it already melted, but it has boiled too. Sulfur, on the other hand, is a solid at room temperature. So, clearly the intermolecular attraction forces in sulfur are much stronger than those in oxygen. Both oxygen and sulfur are molecular compounds.
