Answer:
Through its features.
Explanation:
If a substance contains ionic bonds, then it's properties would include high melting and boiling point, form crystals, hard and good conductors of and electricity while on the other hand, if a substance contains covalent bonds, then it's properties would include soft structure, low melting and boiling points, did not form crystals and poor conductor of heat and electricity so we can conclude that properties of covalent and ionic compounds helps in determining the bonds exists between them.
