Описание слайда:
Lead minerals are easier to mine and lead is easier to extract from its ores than many other metals, which makes the resulting metal relatively inexpensive. For example, lead is used in building construction, lead–acid batteries, bullets and shot, weights, as part of solders and as a radiation shield.

Описание слайда:
Compounds of lead Compounds of lead exist in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. Various oxidized forms of lead are easily reduced to the metal. An example is heating PbO with mild organic reducing agents such as glucose. A mixture of the oxide and the sulfide heated together will also form the metal.

Описание слайда:
Lead is a toxic substance which affects the accumulation of a number of body systems and is especially harmful to young children. Lead is a toxic substance which affects the accumulation of a number of body systems and is especially harmful to young children. Lead is a naturally occurring toxic metal that is found in the earth's crust. Widespread use it caused large-scale environmental pollution, the impact on people and the significant public health problem in many parts of the world. Lead Pollution and its compounds metallurgical industry determined by the specifics of their production activities.
