Explanation:

Step1: Define bond - type properties

Ionic bonds have strong electrostatic forces between ions, covalent bonds have shared electrons. Physical properties reflect these forces.

Step2: Melting - point evidence

Ionic bonds have high melting points due to strong ion - ion attractions. Covalent compounds (many) have low melting points as intermolecular forces are weaker. But some covalent network solids have high melting points.

Step3: Solubility evidence

Ionic compounds are often soluble in polar solvents as water can separate ions. Some covalent compounds are soluble due to polarity or hydrogen - bonding, non - polar covalent compounds are insoluble in water.

Step4: Conductivity evidence

Ionic compounds conduct electricity in molten or aqueous state as ions are free to move. Covalent compounds generally do not conduct as they lack free - moving charged particles, except for some with delocalized electrons (e.g., graphite).

Step5: Complete the CER

Claim: Physical properties can be used to identify bond type because different bond types result in different physical properties due to the nature of the bonding forces.
Evidence 1: Ionic bonds have high melting points and many covalent compounds have low melting points (except network covalent).
Evidence 2: Ionic compounds are often soluble in polar solvents, covalent compounds' solubility depends on polarity.
Evidence 3: Ionic compounds conduct in molten/aqueous state, covalent compounds usually do not.
Reasoning 1: High melting points suggest strong bonding forces like in ionic compounds. Low melting points may indicate weak intermolecular forces in covalent compounds.
Reasoning 2: Solubility in polar solvents implies the presence of charged species or polar bonds.
Reasoning 3: Conductivity requires free - moving charged particles, which are present in ionic compounds in certain states but not usually in covalent compounds.
