Is thulium man made?

Thulium is a lanthanide element, it has a bright silvery-gray luster and can be cut by a knife. Naturally occurring thulium is made entirely of the stable isotope Tm-169.

What is the meaning of atomic number 69?

Thulium
Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices, and in some solid-state lasers.

What are the properties of the element promethium?

Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below. Promethium is named after Prometheus of Greek mythology who stole fire from the Gods and gave it to humans.

Where is promethium most commonly found in nature?

The role of the element in humans, animals and plants. Where the element is most commonly found in nature, and how it is sourced commercially. The image is based on a scene from an Ancient Greek vase. It depicts the god Atlas witnessing Zeus’ punishment of Prometheus. Prometheus was chained to a rock on a mountain top.

What is the state of matter of helium?

What is the state of matter of helium? At room temperature helium is an odorless, tasteless, colorless gas. It has very low boiling and melting points, meaning that it is generally found in the gas phase except under the most extreme of conditions. Click to see full answer.

How is Prometheus used as a radioactive metal?

Prometheus was chained to a rock on a mountain top. Every day an eagle tore at his body and ate his liver, and every night the liver grew back. Because Prometheus was immortal, he could not die, but he suffered endlessly. A radioactive metal. Most promethium is used only in research. A little promethium is used in specialised atomic batteries.

What is the boiling point of promethium at room temperature?

Its electronegativity according to Pauling, ionic radius, and Van Der Waals radius are unknown. The metal is in solid state at room temperature, and its boiling point is 2460 °C. The chemical properties of promethium are little studied because it is radioactive.

Where does promethium come from in the periodic table?

What is Promethium? Promethium (atomic number 61, symbol Pm) is a metal that rarely occurs in nature. It is an artificially produced and radioactive element and earth metal. It can be obtained from fission products of other elements, including plutonium, thorium, and uranium.

What are the two allotropic phases of promethium?

Two allotropic (structural) modifications of promethium are known: the α-phase is double close-packed hexagonal with a = 3.65 Å and c = 11.65 Å at room temperature. The β-phase is body-centred cubic with a = 4.10 Å (estimated) at 890 °C (1,634 °F).

Are there any stable isotopes of promethium?

Over 30 compounds of promethium have been created so far, including binary compounds with hydrogen, oxygen, and halogens. Promethium salts have a greenish or pale blue glow. The element has no stable isotopes and its nuclear isomers are 18 in total.
