Erbium is never found as a free element in nature. It is found in minerals that include all the rare-earth elements. Erbium is one of the more abundant rare-earth elements.
What mineral is terbium in?
Along with other rare earth elements, terbium can be found in minerals, including cerite and gadolinite. The element can be extracted from monazite, in which it is present to the extent of 0.03 percent; from euxenite, a complex oxide containing 1 percent or more of terbia; and xenotime.Is terbium a actinide?
The valence electrons of the terbium element enter into 4f-orbital so the terbium is not an actinide. It is a lanthanide.
Is antimony a metal?Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. … A lead-antimony alloy is used in batteries.
Article first time published onIs lutetium a metal?
lutetium (Lu), chemical element, a rare-earth metal of the lanthanide series of the periodic table, that is the densest and the highest-melting rare-earth element and the last member of the lanthanide series. In its pure form, lutetium metal is silvery white and stable in air.
Is francium a metal?
francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. It exists only in short-lived radioactive forms.
What state of matter is erbium?
Erbium is a chemical element with symbol Er and atomic number 68. Classified as a lanthanide, Erbium is a solid at room temperature.
Is Erbium a noble gas?
The ground state electronic configuration of Neutral Erbium atom is [Xe] 4f12 6s2. The portion of Erbium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Xe].
Is thulium a metal?
A bright, silvery metal. When irradiated in a nuclear reactor, thulium produces an isotope that emits x-rays. A ‘button’ of this isotope is used to make a lightweight, portable x-ray machine for medical use. Thulium is used in lasers with surgical applications.

Why is erbium expensive?
Erbium is another illustrious member of the Rare Earth Gang. The exceedingly difficult task of separating it from the other rare earths is what makes it rare and expensive. The very few uses that have been found for this metal rest solely in its oxides or alloys.
Why is Erbium used in lasers?
Erbium Lasers are used to treat skin problems. The lasers have been used to remove wrinkles and scars. They work better than other kinds of lasers because they do not penetrate the skin very deeply. They also produce little heat and cause few side effects.
