Does alkali metals occur freely in nature?
Compounds, or minerals. The most common is the sodium chloride found in sea water. They are too reactive to be found as free elements.
Why you cant find alkali earth metal free in nature?
because they are so reactive ,, we can find it in earth crust
How is the alkali metal family different from all other families on the periodic table?
Alkali metals are very reactive, easily react with water, the have the valence is +1, they doesn't exist free in the nature, etc.
Why are alkali metal such as sodium not found in nature?
Sodium (Na) is a highly reactive element so it cannot be found in free state but we can have it in compound form like NaCl.
Why is alkalai metals in the periodic table very reactive?
Alkali metals are very reactive.They have free electron in their outermost shell which is responsible for high reactions.For example : Lithium metal.
Why are alkali metals stored in oil and kerosene?
They are so reactive they even react with the moisture in the air. Storing under oil prevents this.
Is alkali dairy free?
Yes, it is.
Explain why alkali metals are not found in free state in nature?
Alkali Metals belong to group 1 of periodic table. They have one electron in last or valence shell and are highly electropositive and have low value of Ionisation enthalpy. So the removal of last electron to form a cation(positively charged ion) is very easy and needs less energy as compared to other elements. As a result of this Alkali metals are highly reactive and readily form ionic compounds. Due to this they react with other elements or compounds and form ionic compound. Hence, they are found in their compounds and not in free state.
Do alkali metals have metallic luster?
All Alkali metals show metallic lustre ,which can be explained by the oscillation of free electrons.

Why potassium is not found in free state in nature?
Potassium, like all alkali metals (Na, Cs, Li) are much too reactive with water (explosive) and oxygen (self ignition). They are only kept as metal elements when UNDER paraffin oil to exclude H2O and O2.
