MENU: Lead Atom

The lead symbol on the periodic table of elements is Pb. The atomic number is 82 and the atomic weight is 207.2(1).This is a shell atom of lead. The heat of fusion is 4.799 kJ/mol. The heat of vaporization is 177.70 kJ/mol. But wait there is more heat stuff coming… the heat atomization is 196 kJ/mole atoms! There are three ionizations: •1st ionization energy 715.6 kJ/mole Electronegativity 2.1 •2nd ionization energy 1450 kJ/mole Electron affinity 35.1 kJ/mole •3rd ionization energy 3082 kJ/mole Specific heat 0.13 J/gK There are also three radiuses: Ionic radius (2- ion) pm Ionic radius (1- ion) pm Atomic radius 146 pm Ionic radius (1+ ion) pm Ionic radius (2+ ion) 133 pm Ionic radius (3+ ion) pm The electron configuration is [Xe] 4f14 5d10 6s2 6p2. In everything there is minimum and maximum including lead. The minimum oxidation is -4 and guess what maximum is… 4 because if the minimum is a negative number then the maximum is the same number without a little dash in front of it. But if it includes the word “common” it is different. See. The minimum common oxidation is 0 but the common oxidation is 4. The structure fcc (which stands for “face-centered cubic color”) is gray. It can be found in stuff like batteries, solder, and paints toxity. The thermal conductivity is 35.3 J. The number of isotopes is 4 Hydride(s) PbH4. But wait, there is more. The hardness is mohs and the characteristics are soft.
