Front

What is a characteristic property of ionic compounds?

Back

They typically have high melting and boiling points.

Front

What is a characteristic property of covalent compounds?

Back

They usually have lower melting and boiling points compared to ionic compounds.

Front

What is the difference between a molecular compound and an ionic compound?

Back

Molecular compounds consist of molecules formed by covalent bonds, while ionic compounds consist of ions held together by ionic bonds.

Front

What is the significance of valence electrons in bond formation?

Back

Valence electrons determine how atoms bond with each other, influencing whether they form ionic or covalent bonds.
