The lab question is “based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? ” fill in the box to answer this question with a hypothesis. hypothesis: if a substance contains ionic bonds, then its properties would include . .

The bonds between ionic molecules are very strong. The ionic molecules are crystalline solid, have high boiling point, and show electric conductivity in the solution.

Ionic Bond:

This bond is formed between two ions where one is positive and another is negative. Positively charged elements give electrons to negatively charged elements to complete octet.

Example:

Properties of Ionic Compound:

Properties of covalent Compound:

Hence, If a substance contains ionic bonds, then its properties would include solid crystalline state, high melting point and conduct electricity in the solution.
