What is the 65th element?
Terbium, element number 65, is no different and lies in the middle of the lanthanide series in between gadolinium and dysprosium. It is one of the rarer rare earth elements, although it is still twice as common as silver in the Earth’s crust.
What is the 68th element?
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.

Who discovered holmium 67?
Per Theodor Cleve
Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element. Holmium was discovered through isolation by Swedish chemist Per Theodor Cleve and independently by Jacques-Louis Soret and Marc Delafontaine, who observed it spectroscopically in 1878.

Does terbium glow in the dark?
Mosander named terbium and erbium after the Ytterby Mine in Sweden, the source of gadolinite mineral they were discovered in. (The elements yttrium and ytterbium were also named after the same mine.) When terbium glows green under ultraviolet light, we know endospores are present.
What is Samarium used for?
Samarium is used to dope calcium chloride crystals for use in optical lasers. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide finds specialised use in glass and ceramics.
