the incomplete table below shows selected properties of compounds that have ionic, covalent, or metallic bonds.\nrow bond electrical conductivity likely property\n1 ionic yes high melting point\n2? yes?\n3? no?\nwhich information would best fill the blanks in row 3?\nmetallic bond and low melting point\nmetallic bond and high melting point\ncovalent bond and low melting point\ncovalent bond and high melting point
Answer
Explanation:
Step1: Recall bond - conductivity properties
Ionic compounds conduct electricity when molten or in solution due to mobile ions. Metallic compounds conduct electricity due to delocalized electrons. Covalent compounds generally do not conduct electricity because they do not have freely - moving charged particles. So, row 3 must be a covalent bond.
Step2: Recall melting - point properties
Covalent compounds usually have relatively low melting points because the intermolecular forces between covalent molecules are weak compared to ionic and metallic bonds.
Answer:
covalent bond and low melting point
