∙ 16y agoOsmium has. Gold and iridium are up there too. Lead isn't even close.
The atomic symbol of osmium is Os. The Atomic number of Osmium is 76. The atomic weight of Os is 190.23 grams per mole. 99% pure Osmium powder is around $100/gram.See the Web Links to the left of this answer for a periodic table with more information about this element!
The elements in group 8 of the periodic table are iron (Fe), ruthenium(Ru), osmium(Os), and hassium(Hs). All four of these elements are grouped together because each of their atoms has a full valence shell containing the maximum of 8 electrons. Atoms seek to bond when their outer valance is unstable and has less than 8 electrons. Their goal is to fill the valance with 8 electrons to become chemically unable to bond or "chemically inert." That is the case with the group 8 elements. They have a complete or closed shell and that is why they do not bond with other elements.

D block metals have these properties. Fe,Cu,Ni,Ti are few examples for them.
yes, the PC will have more than one OS. in my PC i have 3 OS
