[Chemistry Class Notes] on Ununoctium Pdf for Exam

A table of elements, in which they are displayed according to their atomic number, electron configuration, and chemical properties, is called the periodic table. Rows and columns present in the periodic table are called the Periods and groups respectively. There are seven periods in the periodic table. Metals are displayed on the left side, and Non-metals are displayed on the right side. There are 18 groups in the periodic table.

Chemical elements can be in the form of solid, liquid or gas. Till now, 118 chemical elements are identified, in which 94 elements are found naturally on the earth, and the remaining 24 elements are synthetic elements. Every element has its own properties and importance. Today, we will talk about such element whose name is Ununoctium.

Ununoctium – Ununoctium is a synthetic element which can’t be found freely on the earth. Ununoctium is an artificial element which is unstable. Currently, Ununoctium is the only synthetic element of group 18. Basically, Ununoctium belongs to the noble gas. Ununoctium is a temporary name which is taken from the Latin language whose meaning is one-one-eight. 

Ununoctium was the temporary name of this element. In the present, this element is known as Oganesson. This name is given to give the honor to the nuclear scientist Yuri Oganessian who played a very big role in the discovery of this element. Oganesson is the only element whose namesake is alive today

Till now, Ununoctium has the highest atomic number and highest atomic mass among the elements which are discovered. The atomic number of Ununoctium is 118, and the symbol of Ununoctium is Uuo. The Energy of First Ionisation of Ununctium is 839.4 kJ/mol.

Properties of Ununoctium element – The atomic mass of Ununoctium is 294g/mol. Ununoctium belongs to Halogen category. The atomic mass, Melting Point, Boiling Point, Crystal Structure, Density, and color of Ununoctium is unknown. There is no isotope of Ununoctium element.

History and Discovery of the Ununoctium Element – Ununoctium element was discovered on the 19 July 2002 by the scientists who are working at the joint institute for Nuclear Research in the Dubna and Russia along with the scientists from the United states of America, Department of Energy Lawrence Livermore National Laboratory. 

Ununoctium element is produced by bombarding atoms of californium-249 with ions of calcium-48. This process was done under some experienced Scientists. This process produced the ununoctium-294, an isotope with a half-life of about 0.89 milliseconds (0.00089 seconds), and three free neutrons. During the discovery of Ununoctium, the californium target was irradiated with a total of 1.6 x 10¹⁹ calcium ions. This complete process took over 1080 hours of time. This process gives three atoms of Ununoctium.

Uses of Ununoctium Element – There is no use of Ununoctium apart from basic science research. Ununoctium is harmful due to its radioactivity.
