Density of lead

Density of lead

Lead is a silver white or light gray metal, chemical symbol Pb, English name lead
Lead is the 82nd element in the periodic table of chemical elements, with atomic weight of 207.2, density of 11.34 and low melting point of 327.5 ℃. When heated to 400-500 ℃, a considerable amount of lead smoke escapes. Lead vapor is rapidly oxidized into lead oxide in the air and agglomerates into lead dust. Lead can combine with other substances to form lead containing compounds and lead salts, The common ones are pure white basic lead carbonate, pink lead arsenate, yellow lead chromate, black crystal lead sulfide and brown lead dioxide
It is brown crystal. Lead oxide is red (commonly known as red lead) and lead oxide is yellow (commonly known as lead yellow, yellow lead and mithushen). Lead has soft texture and good ductility. It can be rolled into lead skin and lead foil at room temperature. Lead is resistant to chemical corrosion and can effectively absorb short wave electromagnetic radiation. Lead is a kind of non degradable environmental pollutant, once it is mined out, it can be used as an environmental pollutant, You can burn it and bury it, but it will not disappear. One quarter of it can be recycled by human beings, and the other three quarters pollute our environment in different forms
Lead can accumulate in environment for a long time and enter human body through digestive tract and respiratory tract
