Answer:
a. bond angles c. bond length
Explanation:
Models are abstractions of the real world. They are used to present either real or hypothetical situations either visually, graphically or through mathematical expressions.
- In chemistry, to show bond angles and bond lengths, different models are used.
- One of such is the VESPR - valence shell electron pair repulsion- theory which the model upon which the bond relationships between elements in a compound is shown.
- Also, the hybridization schemes are excellent models for showing bond relationships.
