Study Notes
Alkali Metals
- Alkali metals react vigorously with water, producing hydrogen gas. Lithium, sodium, and potassium are examples.
- The reaction forms metal hydroxides, which are strong bases.
- Group 1 metals are stored in oil to prevent reaction with oxygen and water vapor.
- Reactivity increases down the group due to increasing numbers of electron shells.
- Alkali metals are named for the alkaline solutions they produce in water.
- Reactivity increases as atomic size grows, the outer electron is further from the nucleus making it easier to lose
- Hydrogen gas reacts with the alkali metals.
