Osmium's quite possibly the densest element
and my tetroxide's extremely dangerous
my isotope OS-187 can easily pay your rent
cause a pure gram sells for 28,000 dollars US

for fountain pen tips and fingerprinting
the highest melting point of metals in my Platinum family
my oxides really powerful and gives off quite a reek
Osmium's from the word osme a smell if you speak Greek

so we're off to find the metal
the wonderful metal Osmium
because because because it makes other alloys so hard
for high wear applications and chemical synthesis oxidations
Osmium's also great for certain geological period dating
