Properties of Ununpentium

Ununpentium is a highly super heavy and an artificially produced radioactive element that has an atomic number of 115 and a symbol of Uup. It was discovered by bombarding the atoms of the element Americium-243 with the ions of calcium-48. Among the product produced as a result of bombardment were the four atoms of ununpentium and which in about less than 1/10 second got decayed into the atoms of ununtrium.

The element is characterized as a metal and is known to exist as solid in nature at the room temperature. It decays quickly within no span of time into the other elements such as the ununtrium. Ununpentium has about four isotopes with their known half-lives, of which the most stable isotope is the 289 Uup, which has an half-life measuring of about 220 milliseconds.

Ununpentium is assumed to be the third member of the 7p block of chemical elements and is known to be the heaviest member of the group 15 coming in the Periodic Table. A group of Scientists discovered the element from the Joint Institute for Nuclear Research in Russia, and the Lawrence Livermore National Laboratory in the California in the year 2003.

Ununpentium Uses

Only a few atoms of ununpentium have been created, so they are only used for the purpose of scientific study. It is also used to make metal ununtrium. It has no any biological role. But since the metal is said to be highly radioactive, it is considered to be harmful in nature.
