Let's see what we notice from this periodic table. First of all based on wikipedia we can determine some important for different reasons metals:
Malleabillity: gold, tin, aluminum
Deansity: Osmium, Iridium, Uranium
electrical conductivity: silver, copper, gold
thermal conductivity: diamond(carbon): silver, copper, gold
base metals: iron, nickel, lead, zinc, copper
ferrous metals: iron, steel(carbon)
noble metals: tantalum, gold, platinum, rhodium
precious metal: gold, silver, palladium, ruthenium, rhodium, indium, plutonium, uranium
"astronomy" metal: neon, flourine, oxygen
other polular metals are: cobalt, titanium, cadmium, mercury
Let's thus see how and if these metals are encoded in the GP courses. A match is considered in both average atomic weight(avg) or most abundant isotope atomic weight(iso). Local maximums and local minima are considered. If neither average atomic weight or most abundant isotope atomic weight matches I post the relative isotope that matches:
gold (iso + avg almost max : difference 0.4", Jomard+Le Pere max)
tin (iso max)
aluminum (29Al Radiosotope min, Jomard max, Le Pere min)
osmium (iso min + avg different min)
iridium (avg min)
uranium (not applicable)
silver (iso min + avg max)
copper (iso min + avg max)
iron (Fe54 max, Fe57 min, Fe58 almost max: difference 0.1")
nickel(avg max)
lead (not applicable)
zinc (iso min + avg max)
carbon (iso min + avg min)
tantalum (Ta180 0.012% abundance max)
platinum (iso min + avg min)
rhodium (iso max)
palladium (avg almost min: difference 0.2", iso Pd108 2nd by only 2.87% less abundance max)
ruthenium (iso min)
indium (iso min + avg min)
plutonium (not applicable)
neon (iso min + avg min)
flourine (avg+iso max)
oxygen (O17 abundance 0.038% min)
cobalt (avg+iso max)
titanium (avg+iso almost max: difference 0.1", Jomard+Le Pere+Smyth max)
cadmium (avg max)
mercury (avg min + iso min)
There are also other important metals like Caesium. Accourding to wikipedia:
Caesium is also used in atomic clocks, which are accurate to seconds over many thousands of years. Since 1967, the International System of Measurements has based its unit of time, the second, on the properties of caesium. The International System of Units (SI) defines the second as 9,192,631,770 cycles of the radiation, which corresponds to the transition between two hyperfine energy levels of the ground state of the 133Cs atom.
The 133rd GP course is a local minimum. Due to differences between surveys especially courses around the 48th (titanium), the 27th (aluminum), and the 197th (gold) should be remeasured.
