In 2016, four new elements were added to the modern periodic table, thus completing the seventh period of the periodic table. Choose the odd one among the below elements that does not belong to the list of newly added elements : 

The correct answer is Livermorium.

Key Points

• Livermorium (Lv) is not one of the elements newly added to the modern periodic table in 2016.
• Livermorium was officially discovered and added to the periodic table in 2012.
• The four new elements added in 2016 were Moscovium (Mc), Tennessine (Ts), Oganesson (Og), and Nihonium (Nh).
• Livermorium belongs to the same group as Moscovium but was discovered earlier.

Important Points

• The modern periodic table was updated in 2016 with the addition of four new elements, completing the seventh period.
• These elements were officially recognized by the International Union of Pure and Applied Chemistry (IUPAC).
• The naming of these elements honors contributions by researchers and the regions where they were discovered.

Additional Information
