WebA The element with 82 protons (atomic number of 82) is lead: Pb. B For the first isotope, A = 82 protons + 124 neutrons = 206. Similarly, A = 82 + 125 = 207 and A = 82 + 126 = 208 for the second and third isotopes, respectively. The symbols for these isotopes are and which are usually abbreviated as 206 Pb, 207 Pb, and 208 Pb. Exercise WebWhich atoms have the same number of valence electrons? f.
