Factors Influencing Chemical Reactivity
- Chemical reactivity can be influenced by several factors, including temperature, concentration, and surface area, with the concentration often having a significant impact.
- Reactivity is often linked to the nature of the bonds that hold the molecules together, with weaker bonds typically resulting in higher reactivity.
Substances with Higher Chemical Reactivity
- Substances with a higher number of unpaired electrons or those that can easily lose or gain electrons tend to have greater chemical reactivity.
- Alkali metals, for example, are highly reactive due to their single valence electron.
Indicators of Chemical Reactions
- A common indicator of a chemical reaction includes the release of gas, changes in color, temperature variations, or the formation of a precipitate.
