Chemical reactions of the element lead

The surface of metallic lead is protected by a thin layer of lead oxide, PbO. Only upon heating lead to 600-800°C does lead react with oxygen in air to from lead oxide, PbO.

Finely divided lead powder is a fire risk.

The surface of metallic lead is protected by a thin layer of lead oxide, PbO. It does not react with water under normal conditions.

Lead metal reacts vigorously with fluorine, F2, at room temperature and chlorine, Cl2, on warming to form the poisonous dihalides lead(II) fluoride, PbF2, and lead(II) chloride, PbCl2, respectively.

The surface of metallic lead is protected by a thin layer of lead oxide, P

A. Ways in which lead enters the body

Lead used to be an important part of our world. We used it in many things but have recently found the effects of it to be very unhealthy. Lead effects our environment in many way by getting in the air and polluting it and being in paints, drinking water, and in our gasoline. Lead has damaged our environment a lot but we have now learned how and what to control.

A very common place where children can be infected by lead poisoning is on public playground equipment. This is possible if the equipment has chipping or peeling lead paint, which is potential lead poisoning hazard primarily for children six years old and younger. They ingest the lead by getting paint chips or dust on their hands and then putting their hands into their mouth. To solve this problem, it is recommended that you keep the lead at or below the 0.5 percent level.

One of the greatest steps in protecting children's health was the ban on lead in gasoline twenty years ago resulting in a 98% reduction in lead levels in the air and protecting millions of children from serious, permanent learning disabilities by helping to reduce blood lead levels by 75 percent, according to CDC data. Other important steps include the Consumer Product Safety Commission's ban on lead in paint, as well as bans on lead soldered food cans and the use of lead in residential water systems.
