List three properties that you can use to classify a compound as ionic or covalent?

Answer 1

melting points, solubility, and electrical conductivity

Answer 2

1. Electronegativity difference between the bonded atoms: Ionic compounds typically have a large electronegativity difference, while covalent compounds have a smaller or no significant electronegativity difference.
2. Bonding behavior: Ionic compounds involve the transfer of electrons from one atom to another, resulting in the formation of ions, whereas covalent compounds involve the sharing of electrons between atoms.
3. Physical characteristics: Ionic compounds tend to have high melting and boiling points, are often soluble in water, and conduct electricity when dissolved or molten. Covalent compounds, on the other hand, have lower melting and boiling points, are often insoluble in water, and do not conduct electricity.
