A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element.
Lead (82 Pb) has four observationally stable isotopes: 204 Pb, 206 Pb, 207 Pb, 208 Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide.The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series ...

207 (two hundred [and] seven) is the natural number following 206 and preceding 208. It is an odd composite number with a prime factorization of 3 2 ⋅ 23 {\displaystyle 3^{2}\cdot 23} . In Mathematics
The "chart" actually consists of a pair of charts: one, the individuals chart, displays the individual measured values; the other, the moving range chart, displays the difference from one point to the next.
"Lonesome 7-7203" was Hawkins's first chart entry since "Soldier's Joy" in 1959. It spent 25 weeks on the Billboard Hot Country Singles charts, peaking at No. 1 on the chart dated for May 4, 1963. [3] Three days after its release, Hawkins died in an airplane crash which also killed Patsy Cline and Cowboy Copas. Two weeks after Hawkins' death ...
Lead–lead dating is a method for dating geological samples, normally based on 'whole-rock' samples of material such as granite.For most dating requirements it has been superseded by uranium–lead dating (U–Pb dating), but in certain specialized situations (such as dating meteorites and the age of the Earth) it is more important than U–Pb dating.
The C207/A207 E-Class shares its platform with the W204 C-Class sedan, featuring identical wheelbases, and similar axle track lengths. [9] While the W212 E-Class sedan is built at the Sindelfingen plant, the E-Class C207 coupé is built in Bremen alongside the W204 C-Class.
