Answer: The correct answer is francium, radium and hassium.
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
For the given options:
Option 1: Carbon, Silicon, and Tin
All these elements belong to Group 14. Thus, they will show similar chemical properties.
Option 2: Helium, Neon and Argon
All these elements belong to Group 18. Thus, they will show similar chemical properties.
Option 3: Francium, Radium and Hassium
Francium belongs to Group 1, radium belongs to Group 2 and Hassium belongs to Group 8. Thus, they will not show similar chemical properties.
Option 4: Manganese, Rhenium and Technetium
All these elements belong to Group 7. Thus, they will show similar chemical properties.
Hence, the correct answer is francium, radium and hassium.
