Where did Per Theodor Cleve discover holmium?
Holmium was discovered in France by the Frenchman Jacques-Louis Soret in 1878. Holmium was discovered by Per Theodor Cleve, a Swedish chemist, in 1879. Cleve used the same method Carl Gustaf Mosander used to discover lanthanum, erbium and terbium, he looked for impurities in the oxides of other rare earth elements. He started with erbia, the oxide of erbium (Er2O3), and removed all of the known contaminants. After further processing, he obtained two new materials, one brown and the other green. Cleve named the brown material holmia and the green material thulia. Holmia is the oxide of the element holmium and thulia is the oxide of the element thulium. Holmium's absorption spectrum was observed later that year by J. L. Soret and M. Delafontaine, Swiss chemists. Today, holmium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO4), a material rich in rare earth elements that can contain as much as 0.05% holmium.
What does lutetium smell like?
Lutetium is a metal and as such, it does not have a smell. Generally, metals are odorless.

What are the intreresting facts about holmium?
Holmium is a member of the lanthanides group. As a curiosity holmium has the greatest magnetic strength between the elements. Applications: as holmium oxide for the calibration of spectrophotometers, neutron adsorbent, lasers, colorant for glass, etc.
What does holmium look like?
Holmium is a rare-earth metal that is silvery white in appearance. It is relatively soft and malleable and can develop a pinkish hue when exposed to air.
