Interesting Facts about Alkali MetalsBecause they are so reactive with air and water, they are generally stored in oil.Cesium and rubidium are used to make atomic clocks. ... Sodium and potassium both play an important role in biological life on Earth. ... Sometimes cesium is also spelled "caesium."More items...
The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
The reactivity of the alkali metals increases down the group. Lithium is the least reactive and potassium is the most reactive of the three. The hydrogen ignites immediately during the reaction between potassium and water with the potassium producing a lilac coloured flame.
Lithium.Uses of Lithium: Lithium is used in lubricants, in batteries, in glass industries, and in alloys of lead, aluminum, and magnesium to make them less dense and stronger.Sodium.Uses of sodium:Potassium.Uses of potassium:Rubidium and cesium.More items...
Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium.Jun 20, 2017
The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.
Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases.
The alkali metals have the following properties in common:they have low melting and boiling points compared to most other metals.they are very soft and can be cut easily with a knife.they have low densities (lithium, sodium and potassium will float on water)More items...
All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.
