Yes, elements have fixed melting points; but some exceptions are with the elements having allotropes (as carbon, sulfur, phosphorous, etc.) - each allotrope has a specific melting point.

Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
What properties do most covalent compounds have in common?
Most molecular compounds do not conduct electricity and have low melting points.
Does magnesium sulfate have a high melting point?
Magnesium sulfate has a high melting and boiling point, as it is made of Ionic bonds which are very strong. A lot of energy is needed to break them. So ionic compounds have high melting and boiling points. See related link for more information.
What are the boiling and melting points of bromine?
Boiling point 58.78°C Melting point 7.2°C
What is the melting and boiling point of silicon?
The melting point of silicon is 1683 K. The boiling point of silicon is 2628 K.
Why do mixtures not have sharp melting points and boiling points?
Because they are not pure compounds !
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
How melting and boiling point are related to stability of a compound?
Thermally unstable compounds are decomposed before melting or boiling.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
How can a substance have no melting point or boiling point?
Example: compounds that are thermally decomposed before a supposed melting or boiling point.
Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points as they are held by very strong electrostatic force of attraction making the compound stable and therefore they require a lot of energy to break.
Is the boiling point of covalent compounds high or low?
high boiling point low melting point
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
Can Filtration can be used to separate mixtures based on their boiling point?
It is not possible; filtration as a separating method is based on the difference between boiling points.
How melting and boiling points are affected by intermolecular forces?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
