Characteristics: Lithium is soft and silvery white and it is the least dense of the metals. It is highly reactive and does not occur freely in nature. Freshly cut surfaces oxidize rapidly in air to form a black oxide coating.
What are five characteristics of lithium?
Between the most significant properties of lithium we find its high specific heat (calorific capacity), the huge temperature interval in the liquid state, high termic conductivity, low viscosity and very low density.
What are 3 characteristics of lithium?
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.
What are the characteristics of the lithium family?
Characteristics and Properties
At room temperature lithium is a soft metal that is silvery-white in color. It is the least dense of the solid elements and is the lightest of all the metals. It has the highest specific heat capacity of any solid element. Lithium is very reactive and flammable.
What are 3 interesting facts about lithium?
Fun Lithium Facts
- Lithium is the lightest metal.
- Lithium has the lowest density of any metal.
- Lithium is a shiny, soft metal which reacts violently with water forming a strong corrosive base.
- Lithium burns with a bright red color.
- Lithium is used extensively in rechargeable batteries.
How do you identify lithium?
lithium (Li), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale.
What properties make lithium useful?
Uses and properties
A soft, silvery metal. It has the lowest density of all metals. It reacts vigorously with water. The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles.
What is the texture of lithium?
Lithium is a body-centered-cubic (bcc) metal, and thus its sheet texture is very similar to other bcc metals (40).
What are Silicons properties?
In this chapter, properties of silicon are explained in detail. Silicon is an abundant element found in the Earth’s crust in various compounds.
1.1. Properties of Silicon.
| Atomic number of Si | 14 | |
|---|---|---|
| Si atoms | 5×1022 | atoms*cm−3 |
| Melting point | 1687 | K |
| Specific density | 2.329 | g*cm−3 at 298 K |
| Specific density (liquid) | 2.57 | g*cm−3 |
What is the odor of lithium?
Lithium is a soft, silver to grayish-white (or yellow if exposed to air), odorless metal, crystalline mass or powder.
What are the characteristics of beryllium?
Characteristics: Beryllium is light, silver-gray, relatively soft metal that is strong but brittle. Beryllium has the highest melting point of the light metals, melting at 1278 oC – considerably higher than, for example, Lithium (180 oC) Sodium (98 oC) Magnesium (650 oC) Aluminum (660 oC) or Calcium (839 oC).
What does lithium look like as an atom?
In the periodic table, it is located in group 1, among the alkali metals. Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water.
| General | |
|---|---|
| Appearance | silvery white/grey |

| Atomic weight | 6.941 amu |
| Atomic radius (calc.) | 145 (167) pm |
What is lithium used for?
Lithium is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes.
How common is lithium in nature?
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.
What makes lithium unstable?
Lithium has only one electron in its outer shell (i.e., valence = +1) which makes the pure metal very unstable and reactive to moisture.
Is lithium an ore?
Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite LiAl(Si2O5)2, lepidolite K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2, spodumene LiAl(SiO3)2 and also subsurface brines. Australia and Chile are the world’s largest producers of lithium.
What is the structure of lithium?
A lithium atom is an atom of the chemical element lithium. Stable lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force.
Where are the main sources of lithium?
Lithium is mined from different sources: brine and hard rock, with others like clay under exploration. About half the world’s lithium comes from groundwater brine, water rich in lithium salt. Groundwater brine is most commonly mined in South America.
What elements does lithium react with?
Lithium metal reacts vigorously with all the halogens to form lithium halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively lithium(I) fluoride, LiF, lithium(I) chloride, LiCl, lithium(I) bromide, LiBr, and lithium(I) iodide, LiI.
What is lithium made of?
The name for lithium comes from the Greek lithos, which means stone. Lithium occurs in most igneous rocks, although it doesn’t occur free in nature. Lithium metal is made by electrolysis of fused lithium chloride.
Is lithium a malleable?
In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.
