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.

What is the melting point of the ionic compound RaCl2?

The melting point of radium chloride is 900 0C.


Why the melting and boiling point of covalent compound are low?

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.


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.


Is a solid with a melting point of 800 degrees Celsius ionic or molecular?

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.
