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

Numerical Answer Type:
Enter a numerical value Answer: 11 to 11 +4 marks

Solution & Explanation

### Core Logic Decode the IUPAC name "Unununnium" into its atomic number. Un = 1 Un = 1 Un = 1 Suffix = ium So, the atomic number is 111. ### Step 1: Finding group number For d-block elements with Z > 100, the group number is the last two digits of the atomic number. Since Z = 111, the element belongs to group 11 (the Copper group). ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 11 Chemistry: Classification of Elements and Periodicity in Properties
