If IUPAC name of an element is "Unununnium" then the element belongs to nth group of periodic table. The value of n is _______.

Correct answer

0

Step-by-step solution

Unununnium is the IUPAC name given to the element Roentgenium and the atomic number 111 . In the periodic table in the 7 th period it is located and placed in the 11 th group. Roentgenium is a radioactive element and its isotopes are unstable in nature. 111 belongs to 11 th group. Hence the value of n is 11 .
