It's likely but not definitive. Giant covalent substances like diamond also have high melting and boiling points. To be sure you would have to show that the melted or dissolved substance conducts electricity.
no, they are two different things. molecular compounds have a lower boiling and melting point relative to ionic.
Ionic compound with high melting and boiling point. This is good example of a salt.
ionic compound tend to have a high melting point because of their high electronegativity.
The melting point of SeF6 is -34,6 oC, the boiling point is - 46,6 oC.
ionic compounds
Brittleness high melting and boiling point are properties of ionic compounds within structures. This is taught in biology.
Ionic compounds generally have higher melting and boiling points.
The melting point of radium chloride is 900 0C.
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
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.
The melting point of a compound cannot determine the bonding structure. As an example, both diamond and sodium chloride have higher melting points than 800 centigrade but are covalent and ionic compounds respectively.
Thermally unstable compounds are decomposed before melting or boiling.
