What is the structure of lead?

Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.

Before explaining why lead is radioactive, I would like to briefly explain what radioactivity is. According to Wikipedia: A large percentage (>98%) of lead ordinarily found in nature is of stable isotopes whereas the rest of its isotopes are unstable. It is the unstable isotopes of lead that are radioactive.

Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is found in lead-based paints, including paint on the walls of old houses and toys.

A lead compound (i.e. a “leading” compound, not to be confused with various compounds of the metallic element lead) in drug discovery is a chemical compound that has pharmacological or biological activity likely to be therapeutically useful, but may nevertheless have suboptimal structure that requires modification to

Even though lead is not magnetic it can interact slightly with magnetic fields. By moving a very strong magnet past a piece lead can actually cause the lead to move. The video below shows that lead does interaction with the magnet, other metals, such as Aluminum, Brass, and, Copper have a more visible interaction.

“Led” in most cases is a verb. It is the past tense and past participle of “lead” as a verb when the pronunciation of “lead” rhymes with “bead.” Consider the following examples: Example 6: She led the team to victory last week in the championship game (“led” is a verb in past tense form).

Mercury can be used to make thermometers, barometers and other scientific instruments. Mercury conducts electricity and is used to make silent, position dependent switches. Mercury vapor is used in streetlights, fluorescent lamps and advertising signs.

It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO4), cerussite (PbCO3) and minum (Pb3O4). Although lead makes up only about 0.0013% of the earth’s crust, it is not considered to be a rare element since it is easily mined and refined.

Lead cation PB4+ Chemical Names: Lead; 7439-92-1; Plumbum; Lead metal; Blei; Lead, elemental More Lead cation PB4+ is a soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.2, symbol Pb.

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

Lead is a soft, ductile, dense and highly malleable metal with a dull bluish-gray colour.

Lead is a naturally occurring metal found in the earth’s crust. Lead can be found many places, much because of human activity through burning fossil fuels, mining, and manufacturing. Water can be contaminated with lead from mines, waste dumps, and industrial plants.

Elementary lead does not dissolve in water under normal conditions (20oC, and pressure = 1 bar). It may however occur dissolved in water as PbCO3 or Pb(CO3)22-. A well-known example of a water soluble lead compound is lead sugar (lead(II)acetate), which derived its name from its sweet nature.

Lead is a reactive metal, but its reactivity is somewhat inhibited by the formation of an outer skin of protective compounds. For example, when a freshly cut piece of lead metal is exposed to the air, it quickly reacts with oxygen to form a thin outer layer of lead oxide.

Galena uses. Galena is the primary ore of lead, which is mainly used in making lead–acid batteries; however, significant amounts are also used to make lead sheeting and lead shot. Galena is often mined for its silver content, such as at the Galena Mine in northern Idaho.

Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent adverse health effects, particularly affecting the development of the brain and nervous system. Lead also causes long-term harm in adults, including increased risk of high blood pressure and kidney damage.

After mixing with limestone the filtered concentrated ore is roasted in air or oxygen-enriched air on a moving belt. Most of the sulfide is converted to lead(II) oxide: Sulfur dioxide gas can then be cleaned and used to make sulfuric acid. The lead(II) oxide is heated and made into lumps, a process known as sintering.

Lead is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and has a relatively low melting point. When freshly cut, lead is bluish-white; it tarnishes to a dull gray color when exposed to air.

Lead (Pb) has an atomic number of eighty-two. It is a highly malleable member of the metal elements and is highly resistant to corrosion. Interesting Lead Facts: Lead has been in use by ancient civilizations for thousands of years, and is mentioned in the second book of the Old Testament.
