Section 2.2 Chemical Properties Solutions and Explanations

Focus on the behavior of substances under various conditions to assess their reactivity and stability. The interaction between atoms or molecules determines the way a material reacts to external stimuli such as heat, pressure, or other substances.

Bond strength plays a major role in determining how tightly atoms are held within a compound. The stronger the bond, the more stable the substance. Conversely, weaker bonds lead to higher reactivity, making these substances more likely to change when exposed to certain conditions.

Electronegativity differences between atoms within a molecule help predict how electrons are shared or transferred. This influences the formation of positive or negative charges, impacting how substances interact with one another in chemical reactions.

Always consider the phase of a substance. Solids typically have limited movement between molecules, while liquids and gases allow for greater mobility, influencing reaction rates and outcomes.
