Periodic Table and Periodicity question

2020 · 3 Sep · Shift 1 · Q6

JEE MainChemistryPeriodic Table and PeriodicityMCQ+4 / −1

The atomic number of the element unnilennium is :

A
109
B
102
C
119
D
108

View written solutionFree

Correct answer: A

Interpret the name

The temporary systematic name unnilennium is formed from Latin/Greek roots for digits:
- un $\to 1$
- nil $\to 0$
- enn $\to 9$
- suffix -ium
Construct the atomic number

Therefore, unnilennium corresponds to the digits:

$109$
Match with the options
- A: $109$ ✅
- B: $102$ ❌
- C: $119$ ❌
- D: $108$ ❌
Conclusion

The atomic number of unnilennium is:

$\boxed{109}$

So, the correct option is A.
