How are lithium atoms bonded in a solid?

Hint: First of all we should know about the Lithium atom and its properties, then its arrangement in a solid. Lithium is a chemical element in a periodic table whose atomic number is 3. It is placed in group one which is an alkali metal group. It is moderately abundant and present in 65 ppm as in earth’s crust.

Complete step-by-step answer:The important uses of lithium are –
It is generally used in rechargeable batteries of phones, digital cameras, laptops and electric vehicles.
It is also used in some non-rechargeable batteries for things such as toys, clocks and heart pacemakers.
Its oxide is generally used in special glasses and glass ceramics.
Lithium stearate is used in all purpose and high-temperament lubricant.
Lithium hydride is used as a means for storing hydrogen as a fuel.
Lithium and bromine are concentrated together to form brine solution. Brine is generally used in the manufacturing of air conditioner systems.
Properties of Lithium
Metallic lithium reacts vigorously with water.
It has very low density and viscosity.
It takes part in both organic as well as inorganic reactions.
Metallic lithium is soluble in aliphatic amines.
Lithium atoms generally form an ionic or electrovalent compound, which is generally formed by the linkage of electrostatic force of attraction.

Note:It is a soft, silvery metal. It has the lowest density among all the metals. It reacts vigorously with water. Lithium has no biological use. It is generally toxic in nature, except in small doses. It is found only in salts and minerals.
