What does Pb-207 mean?

Pb, 207Pb and 208Pb are all radiogenic, and are the end products of complex decay chains that begin at 238U, 235U and 232Th respectively. The corresponding half-lives of these decay schemes vary markedly: 4.47 x 109, 7.04 x 108 and 1.4 x 1010 years, respectively.

Is lead-207 stable?

Lead 207 Metal (Lead-207) is a stable (non-radioactive) isotope of Lead. It is both naturally occurring and a produced by fission.

Is lead 82 stable?

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.

What is the total number of neutrons in an atom of 207 82 Pb?

Thus, 207-Pb has 82 protons and 82 electrons. To determine the number of neutrons, the mass number can be subtracted by the total number of protons. So the isotope has 125 neutrons (207 minus 82).

What element has 82 electrons in its nucleus?

Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82.

What is the atomic number of 207?

Element Name Polonium
Element Symbol Po
Atomic Number 84

Is lead old uranium?

Three stable lead nuclides are the end products of radioactive decay in the three natural decay series: uranium (decays to lead-206), thorium (decays to lead-208), and actinium (decays to lead-207). More than 30 radioactive isotopes have been reported.

Why is lead still used?

The largest use for lead is in storage batteries in cars and other vehicles. Lead compounds are used as a pigment in paints, dyes, and ceramic glazes, and in caulk. Lead paint was banned for consumer use in 1978 in the U.S.; however, it is still used in industrial paints such as those used on cars, bridges, and ships.
