Lithium – A highly reactive alkali metal that is soft enough to be cut using knife – was actually one of the three elements that were produced during Big Bang! Did you know this fact? There are many such interesting Lithium facts that will blow your mind. In this list of 20 facts about Lithium, we are going to find out some interesting information about this amazing metal. You ready?

Lithium Facts: 1-5
1. Lithium stands 3rd in the periodic table with an atomic weight of 6.941 ± 0.002 u. In pure form, Lithium is highly reactive but it is list reactive when compared to other alkali metals.
2. Lithium’s nucleus is very unstable and because of this, it is almost impossible to find pure Lithium naturally. Natural Lithium can be found as a combination of two stable isotopes which are Lithium-6 and Lithium-7. Of the two, Lithium-7 is abundantly present (92% natural abundance) than Lithium-6. There are three radioactive isotopes of Lithium.
3. The word “Lithium” originated from the Greek word “lithos” which means stone. It is the lightest known metal known to man. Water is two times denser than Lithium.
4. Lithium is the first member of its group – alkali metals. Other alkali metals are Sodium, Potassium, Rubidium, Caesium and Rancium.
5. Its color is silver-white. Though it is a metal, it is so soft that you can literally cut the element using a knife. This metal is one of the few metals which have a very low melting point and very high boiling point.
Lithium Facts: 6-10
6. Did you know that it is tough to find Lithium in free state? It is present in rocks, mineral springs etc. but not in free state. This is due to the fact that it is extremely unstable and highly reactive. We already mentioned this earlier. Sorry for repeating!
7. Owing to its high reactivity with almost anything, even water and air, it is stored in oil or in an inert atmosphere.
8. Lithium is the only metal which reacts with Nitrogen naturally. Though it reacts with water, its reaction is least violent.
9. Just like Sodium, Lithium actively reacts with water and forms Lithium Hydroxide and Hydrogen which burns into a crimson red flare.
10. It usually doesn’t react with Oxygen but given a temperature above 100 degrees Celsius, it forms Lithium Oxide.
