because when they come contact with air they absorb energy get excited and come to ground state while coming to ground state they radiate energy for this they shine in nature
Alkali metals are not found as pure elements in nature.
All alkali metals exist in nature as compounds.
Alkali Metals: the alkali metals are found in the first group of the periodic table, Alkali metals are very reactive metals and they are not freely in their nature, alkali metals have one electron in their outermost shell. therefore alkali metals are ready to loose that one electron for bonding with other elements, alkali metals are good conductor of electricity and heat. they are soft in nature than other metals.The Alkali Metals are:lithium, sodium, potassium, rubidium cesium, francium
The alkali metals are all very recative and are not found free in nature (pure elemental form) but are always found as compounds. (minerals)
Highly reactive
Alkali metals, such as sodium and potassium, are so reactive that they are never found as uncombined elements in nature. They readily react with other elements to form compounds.
The name "Alkali" is given due to the alkaline nature of their oxides and hydroxides. The term "Alkali Earth Metals" is used as these metals are usually found as minerals in the Earth's crust.
They are very reactive
alkaline earth metals
Francium is considered the hardest metal in Group 1 (alkali metals). It is the most reactive alkali metal and is very rare in nature. Due to its high reactivity and radioactive nature, it is challenging to study and handle francium.
alkali metals are highly reactive especially with water so they tend to form compounds in nature.
Yes, alkali metals like sodium and potassium are found in nature. They are often found in minerals and salts, and they are quite reactive due to their tendency to lose one electron and form positive ions.
