The International Union of Pure and Applied Chemistry (IUPAC) has announced four proposed names for the four new elements that were added in periodic table in January 2016.
• These names and symbols were chosen by the by nuclear researchers who discovered them. They will be finalised after public review and formal nod by the IUPAC Council.
• All these four elements are super heavy and are synthetic in nature i.e. they were created in laboratory.
• These new elements are Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og).
• They were added in the seventh row of the periodic table. Their addition has completed the seventh row of the periodic table of the elements.
Atomic No – 113 – Nihonium – Nh .
Atomic No – 115 – Moscovium – Mc
Atomic No – 117 – Tennessine – Ts
Atomic No – 118 – Oganesson – Og
• IUPAC is panel of scientist that governs chemical research and the admission of the new elements in the periodic table.
• Under it rules, names of the elements must reflect one of the physical characteristics or chemical properties, a place, a mineral, a scientist (living or dead), or a mythological concept.
• The names of elements is finalised by IUPAC which are easy to translate across major languages. The names usually have endings like “-ine”, “-ium,” or “-on,” depending on the grouping of elements they belong to.
