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

Are alkali metals always found pure in nature?

Alkali metals are not found as pure elements in nature.


Which is an example of an alkali metal that does NOT exist independently in nature or in the laboratory?

All alkali metals exist in nature as compounds.


What are some characteristics of alkali metals?

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


Are alkali metals readily available in nature?

The alkali metals are all very recative and are not found free in nature (pure elemental form) but are always found as compounds. (minerals)


Why is it unlikely to find alkali metals in nature?

Highly reactive


What group of metals is so reactive that the metals are never found as uncombined elements in nature?

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.


Why group 2A are called the alkali earth metals?

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.


Why is it unlikely to find pure alkali metals in a nature?

They are very reactive


What is family one called in the periodic table?

alkaline earth metals


Which is the hardest metal in group 1 that is in alkali 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.


Why are elkali metals such as sodium not found in nature as elements?

alkali metals are highly reactive especially with water so they tend to form compounds in nature.


Is alkali metals found on 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.
