Estimates of abundance of the elements in the earth's crust, arranged in order of atomic number [Column numbers indicate references on page 3] Lead is particularly dangerous to children because their growing bodies absorb more lead than adults do and their brains and nervous systems are more sensitive to the damaging effects of lead. Babies and young children can also be more highly exposed to lead because they often put their hands and other objects that can have lead from dust or soil on them into their mouths.

Volume-fraction is a common abundance measure in mixed gases such as planetary atmospheres, and is similar in value to molecular mole-fraction for gas mixtures at relatively low densities and pressures, and ideal gas mixtures.

Manganese, nickel, copper, cobalt and molybdenum are found in great abundance in marine mineral deposits. Together with other rare earth elements, they  work in China, where we continue to lead panda conservation efforts in close collaboration with abundance and diversity of life on Earth.

On a weight basis, lead has nearly the same abundance in Earth’s crust as tin. Cosmically, there is 0.47 lead atom per 10 6 silicon atoms. The cosmic abundance is comparable to those of cesium , praseodymium , hafnium , and tungsten , each of which is regarded as a reasonably scarce element.

Lead occurs naturally as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%).
