Question:
Which of the following statement is not correct?
Which of the following statement is not correct?
Show Hint
Group 17 contains elements ending with the suffix "-ine" ($\text{F}, \text{Cl}, \text{Br}, \text{I}, \text{At}, \text{Ts}$). Tennessene is a halogen!
Updated On: Jun 3, 2026
- The increasing order of first ionization enthalpy of Be, B, C is $B < Be < C$
- The IUPAC name of element Livermorium is ununhexium
- The element Tennessene belongs to group 16 in periodic table
- $Al_{2}O_{3}$, $As_{2}O_{3}$ are amphoteric oxides

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Elements in the periodic table are assigned to vertical groups based on their valence electronic configuration and atomic number.
Step 2: Meaning
Tennessene (Ts) has an atomic number of 117. It is located at the bottom of the halogen family.
Step 3: Analysis
Let us evaluate the options: * *Ionization Enthalpy:* Be ($1s^2 2s^2$) has a stable, fully-filled subshell, making it harder to ionize than B ($1s^2 2s^2 2p^1$). Hence, $B < Be < C$ is correct. * *IUPAC Name:* Element 116 corresponds to un-un-hex-ium, so this statement is accurate. * *Oxides:* Both alumina and arsenic trioxide display both acidic and basic properties, classifying them correctly as amphoteric. * *Group Designation:* Group 17 consists of halogens. Because Tennessene ($Z=117$) sits directly underneath Astatine, it belongs to group 17, not group 16.
Step 4: Conclusion
The statement claiming Tennessene belongs to group 16 is incorrect.
Final Answer: (C)
