Facts About Rubidium:
It's reacts violently with water, forming corrosive rubidium hydroxide.
Rubidium can also ignite spontaneously in air. It forms alloys with cesium, gold, sodium, and potassium and it forms amalgams with mercury.
Uses of Rubidium:
- Rubidium is used for making glasses, ceramics and in fireworks to add a purple color.
- It is also used as a getter in vacuum tubes to remove trace gasses.

Facts About Lithium:
Lithium is the only alkali metal that reacts with nitrogen.
Lithium based batteries have revolutionized consumer devices such as computers and cell phones. For a given battery weight, lithium batteries deliver more energy than batteries based on other metals; in other words, lithium batteries have high energy density.
Uses of Lithium:
- Pure lithium metal is used in rechargeable lithium ion batteries and the metal is used as an alloy with aluminium (aluminum), copper, manganese, and cadmium to make high performance aircraft parts.
- Lithium also has various nuclear applications, for example as a coolant in nuclear breeder reactors and a source of tritium, which is formed by bombarding lithium with neutrons.
- Lithium carbonate is used as a mood-stabilizing drug.
