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.
Ionic compounds do not have a specific boiling point because they do not exist as individual molecules. Instead, they have a high melting and boiling point as they require a lot of energy to break the strong ionic bonds between the positively and negatively charged ions.
The melting point of SeF6 is -34,6 oC, the boiling point is - 46,6 oC.
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 structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
Because it is a ionic compound.
Thermally unstable compounds are decomposed before melting or boiling.
The ionic bond is stronger.
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
Ionic compounds are basically the combination of a metal and a non-metal. However, its high melting points and boiling points are part of the physical properties of ionic compounds, and high heat is usually required to break the bonds of ionic compounds. The ions which are held together by strong electrostatic force of attraction may results in high melting point and boiling point.
If the melting point is at 1240 degrees C then it is most likely an ionic compound, because ionic compounds have their melting points above 800 degrees C while the molecular compounds have their melting point at or below room temperature.
Sodium chloride is a ionic compound. Generally they have high melting points.
