Japanese scientists first synthesized the 113th chemical element


28/09/2012

A group of Japanese scientists announced the long-awaited synthesis of the elusive chemical element by atomic number 113, ununtriya.

Element 113 - an atom with 113 protons in its nucleus, which was created in the laboratory, as it does not occur naturally. More and heavier elements are synthesized in the laboratory in recent years. The most massive of these, at the moment - the element 118, under the provisional name ununoktium.

If confirmed, it would be the first ununutry chemical element of the system periodically, superiority in the synthesis of which is owned by a Japanese scientist. For the first time in history, the Asian research team is privileged to give the name of the chemical element. Prior to this, only scientists from the U.S., Russia and Germany had the opportunity.

Ununtry - a temporary name denoting one-one-three (113). He is extremely unstable and can only be created in the laboratory. As the research team, they have attempted to create this element for more than nine years before finding the right approach in the past month.

The team, led by Kosuke Morita from the Institute of Physical and Chemical Research RIKEN, pushed zinc (30 protons) and bismuth (83 protons). The result is an atom with 113 protons in the nucleus.

But this new element quickly fell apart. That is the nature of the collapse is proof that they create a new item. Morita said that the data on the decay indicate that in the course of the collision cell was formed with 113 protons.

Most matter of the universe is very simple elements such as hydrogen (one proton), carbon (six protons) and oxygen (eight protons). Each proton usually have an equal number of neutrons and electrons. But the more protons and neutrons of an atom contains a nucleus, the more unstable it becomes an atom. Scientists still have not figured out what is the limit of the atom.

"I would like to thank all the researchers who have made a contribution to the achievement of this important result, which never ceased to believe that one day the 113th will be ours. As a next target, we’ll still uncharted territory, beginning with the element 119 and beyond" .
