Jump to main content Lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity. Name: Lead. Symbol: Pb. Atomic Number: 82. Atomic Mass: 207.2 amu.
A Lead atom, for example, requires the following ionization energy to remove the outermost electron. Pb + IE → Pb+ + e− IE = 7.4167 eV ››More information on molar mass and molecular weight. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on farther and farther from the nucleus. The atomic number of lead is 82, and its atomic mass is 207 g/mol. 207.2 amu is the average weight of a single lead atom. We can also write 207.2 grams as the weight of an Avogadro's number of lead atoms.
It has a melting point of 327 degrees Celsius.

In children the accumulation of lead may result in cognitive deficits; in adults it may produce Lead is a grey, very heavy and soft metal with a low melting point. Amongst others, it is used for weights and for radiation protection. Lead forms in air quickly a protecting oxide layer, which makes it dark. Left: Small lead weight, 0.4 cm.
The Kossel shell structure of lead. Lead is a chemical element with atomic number 82 which means there are 82 protons in its nucleus.

2015-11-22 · 6.6 * 10^(22)"atoms" You know that the mass of an individual lead atom is equal to 3.4 * 10^(-22) grams. A substance's density tells you what its mass per unit of volume is. In this case, you know that lead has a density of "11.3 g/cm"^3, which means that each "cm"^3 of lead will have a mass of "11.3 g". Now, your cube has a volume of "2.00 cm"^3, which means that its mass will be equal to 2
