5/17/2023 0 Comments Li periodic tableBecause of this, lithium reacts easily with water and does not occur as the free element on Earth. Like all alkali metals, it has a single valence electron, and will readily lose this electron to become a positive ion. Though in group 1, lithium also exhibits properties of the alkaline-Earth metals in group 2. Lithium compounds are used pharmacologically as a class of mood stabilizing drugs, a neurological effect of the lithium ion Li +. Lithium metal is used primarily in heat-transfer applications, batteries (mainly cell phone and camera batteries), household appliances such as toasters and microwaves, and in high performance alloys such as those used for aircraft construction. It tarnishes and oxidizes very rapidly in air and water. It therefore has to be stored under the cover of oil to stop this oxidation reaction from occurring. Lithium reacts with oxygen from the air to form black lithium oxide (Li 2O). Lithium in its pure form does not occur naturally on Earth. It is in group 1 of the periodic table, among the alkali metals and is the lightest solid element. Lithium is one of only four elements theorized to have been created in the first three minutes of the universe through a process called Big Bang nucleosynthesis. You can effortlessly find every single detail about the elements from this single Interactive Periodic table.Lithium ( IPA: /ˈlɪθiəm/, from Greek: lithos: stone, because it was discovered in petalite) is a chemical element with the symbol Li and atomic number 3. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). Free Gift for you: Interactive Periodic Table Lithium is so reactive that it is never found in its pure form, but it always exists along with other elements in a compound form.Density of Lithium is around half of that of waters’ density (Density of Lithium = ½ density of water).Lithium is highly corrosive, so it is stored in kerosene oil or it is stored in an inert atmosphere.Lithium is a metal, but it is so soft that it can even be cut using a kitchen knife.Lithium produces crimson red flame when heated in a Bunsen burner.If Lithium catches fire, then you cannot extinguish that fire using water.Lithium is a metal, but it floats on water.The 7 interesting facts about Lithium are mentioned below. Hence, lithium gives crimson red flame when it is heated. This emitted radiation of 670.8 nm is nothing but a visible crimson red light. ![]() ![]() ![]() When this excited electron loses its energy, it again comes back to the lower energy level.ĭuring this phenomenon, it emits an electromagnetic radiation having a wavelength of around 670.8 nm. When Lithium metal is heated in a flame, its outermost electron gets excited onto a higher energy level.
