Thallium is a soft, silver-white metal that is very easy to melt and dissolve in acids. It has the lowest boiling point of any metal other than mercury, and the lowest density of any metal except lithium.
Uses of Thallium
Thallium is a soft, malleable, and silver-white metal that is not found free in nature. It is found in the minerals thallium sulfide (Tl 2 S) and thallium carbonate (Tl 2 CO 3 ). The metal is used in the manufacture of electronic devices, optical materials, and medical equipment.
Physical Properties of Thallium
Thallium is a soft, bluish-white metal that is not found free in nature. It is found in small amounts in minerals such as thallium sulfide (Tl 2 S), which is the main ore from which thallium is extracted.
Thallium is a good conductor of electricity and heat. It is also a very toxic metal.
Chemical Properties of Thallium
Thallium is a soft, malleable, bluish-white metal. It is a poor conductor of electricity, but is a good conductor of heat. It is not attacked by air, water, or most acids, but is soluble in hot concentrated sulfuric acid.
Structure of Thallium
Thallium has a structure that is similar to that of aluminum. It has a metallic core that is surrounded by a number of shells. The core is made up of eight electrons, and the shells are made up of 18 electrons.
