In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.
What are the physical properties of lithium?
Lithium Properties
Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.
Is lithium a metal or nonmetal?
Lithium is a soft, silvery-white, metal that heads group 1, the alkali metals group, of the periodic table of the elements.
Is lithium a good conductor?
Because lithium (like most other metals) easily gives up its “extra” electron, it is a good conductor of electricity.
Is lithium a mineral or metal?
‘stone’) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.

Is lithium malleable ductile or brittle?
In the periodic table, lithium is located in the second period, in the first group, and the element is classified as an alkaline metal. In compounds, lithium displays an oxidation state of +1. In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.
Is lithium an isotope?
Naturally occurring lithium (3Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5332. 3312(3) MeV for lithium-6 and 5606.
Is lithium an anion?
The methyl anion CH3− was the strongest known base before lithium monoxide anion was discovered. LiO− has a proton affinity of ~1782 kJ mol−1.

What type of element is lithium?
alkali metal
A highly reactive and inflammable element, lithium (Li) is the first alkali metal in the periodic table which consists of elements such as sodium (Na). Present all over the world, lithium does not exist in its pure state in nature but can be extracted in small quantities from rock, clay and brine.
What texture is lithium?
Lithium is a body-centered-cubic (bcc) metal, and thus its sheet texture is very similar to other bcc metals (40).
What makes lithium unique among metals?
Lithium is a special metal in many ways. It’s light and soft — so soft that it can be cut with a kitchen knife and so low in density that it floats on water. It’s also solid at a wide range of temperatures, with one of the lowest melting points of all metals and a high boiling point.

Is lithium a solid liquid or gas?
Classified as an alkali metal, Lithium is a solid at room temperature.
Is lithium a natural mineral?
Lithium is a naturally occurring mineral, and trace amounts are present in the water many of us drink.
Is lithium abundant?
Introduction. Lithium is present in the earth’s crust at 0.002–0.006 wt%. It is the 33rd most abundant element in nature and is distributed widely in trace amounts in rocks, soils, and surface, ground, and sea waters.
Is lithium malleable ductile?
In the periodic table, lithium is located in the second period, in the first group, and the element is classified as an alkaline metal. In compounds, lithium displays an oxidation state of +1. In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.
Is lithium a density?

| Density | Name | Symbol |
|---|---|---|
| 0.534 g/cc | Lithium | Li |
| 0.862 g/cc | Potassium | K |
| 0.971 g/cc | Sodium | Na |
| 1.55 g/cc | Calcium | Ca |
Why are metals malleable?
Metals are malleable – they can be bent and shaped without breaking. This is because they consist of layers of atoms that can slide over one another when the metal is bent, hammered or pressed.
Which of the following is an isotope of lithium?
The two isotopes of lithium are lithium-6 and lithium-7.
Why is lithium used in thermonuclear reaction?
In nuclear reactor, lithium is used as a heat transfer due its boiling temperature (1342°C), making it an excellent thermal conductor.
