Chemistry of Lithium


The discovery of lithium can be traced back to the early 19th century. Swedish chemist Johan August Arfwedson first identified lithium in 1817 while analyzing petalite ore from a mine in Sweden.

He noticed a new element with unique properties, which he named lithium after the Greek word “lithos” meaning stone. Arfwedson’s discovery marked the beginning of the study of lithium and its chemistry.


After its discovery, lithium remained relatively obscure for several decades. It wasn’t until the late 19th century that scientists began to explore its potential applications.

In 1855, British chemist Augustus Matthiessen isolated pure lithium metal for the first time. Lithium’s low density and high reactivity intrigued researchers, leading to further investigations into its chemical properties and potential uses.

Basic Chemistry

Lithium is the third element in the periodic table, with an atomic number of 3 and the symbol Li. It belongs to the alkali metal group, which also includes elements such as sodium and potassium.

Lithium is highly reactive and has a single valence electron, making it prone to forming compounds with other elements. It readily loses this electron to form a positive ion, Li+, which is stabilized by its small size and high charge density.

Physical Properties

Lithium is a soft, silvery-white metal that is the lightest metal and the least dense solid element. It has a low melting point of 180.5°C (356.9°F) and a boiling point of 1,342°C (2,448°F).

Lithium is a good conductor of heat and electricity and exhibits high thermal stability. It is also highly reactive with water, releasing hydrogen gas and forming lithium hydroxide.

Chemical Reactions

Lithium readily reacts with various elements and compounds due to its high reactivity. It reacts vigorously with oxygen, forming lithium oxide (Li2O) or lithium peroxide (Li2O2) depending on the conditions.

Lithium also reacts with nitrogen to form lithium nitride (Li3N) and with halogens to form lithium halides (e.g., lithium chloride, lithium bromide). Additionally, lithium can react with sulfur to produce lithium sulfide (Li2S) and with carbon to form lithium carbide (Li2C2).

Interesting Physical Properties of Lithium

1. Low Density

Lithium is the lightest metal and has a low density, making it highly buoyant in water. Its density is about half that of water, which allows it to float on its surface. This property makes lithium useful in applications where weight reduction is crucial, such as in lightweight alloys and batteries.

2. Softness

Lithium is an extremely soft metal and can be easily cut with a knife. It has a Mohs hardness of 0.6, making it one of the softest elements. Due to its softness, lithium is often used as a lubricant in various industrial processes. Additionally, its malleability allows it to be easily shaped into different forms.

3. Silver-White Appearance

Lithium has a shiny, silver-white appearance, similar to other alkali metals. This characteristic makes it visually appealing and often used in the production of decorative items. However, it quickly tarnishes when exposed to air, forming a dull oxide layer on its surface.

4. High Thermal Conductivity

Lithium exhibits excellent thermal conductivity, allowing it to efficiently transfer heat. This property makes it valuable in various heat transfer applications, such as in heat sinks and cooling systems. Lithium’s high thermal conductivity also contributes to its use in batteries, as it helps dissipate heat generated during charging and discharging processes.

5. Low Melting Point

Lithium has a relatively low melting point of 180.5°C (356.9°F), which is one of the lowest among metals. This low melting point enables lithium to be easily melted and cast into different shapes. It also contributes to its use in the production of alloys and as a coolant in nuclear reactors.

6. Reactivity with Water

Lithium is highly reactive with water, producing hydrogen gas and a strong alkaline solution. When lithium comes into contact with water, it rapidly floats and reacts, releasing hydrogen gas. This reactivity is utilized in lithium-ion batteries, where lithium ions move between electrodes during the charging and discharging process.
