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 Lead - Lead - Properties of the element: Lead and its compounds are toxic and are retained by the body, accumulating over a long period of time—a phenomenon known as cumulative poisoning—until a lethal quantity is reached.

Its official chemical symbol is Pb, and its atomic number is 82, which means that a lead atom has 82 protons in its nucleus. Lead has the highest atomic number of any stable (non-radioactive) element. It is a dense, heavy metal – yet it is soft and can be shaped and stretched without breaking. 2020-07-15 2009-07-28 Lead, 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. Known in antiquity and believed by the alchemists to be the oldest of metals, lead is highly durable and resistant to corrosion.
