Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. The chemical symbol for Einsteinium is Es. Thorium is commonly found in monazite sands (rare earth metals containing phosphate mineral). The noble gas shorthand is used to summarize the electron configuration of an element while providing the most relevant information about the valence electrons of that element. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. Its properties are thus intermediate between those of chlorine and iodine. Looks like Zr since it has 4d2 but is an s block with 2 valence electrons in n=5. The chemical symbol for Scandium is Sc.
