which of the following groups of elements are most likely not to show similar properties?

carbon, silicon, and tin
helium, neon, and argon
francium, radium and hassium
manganese, rhenium, and technetium

Respuesta :

A. carbon, silicon, and tin 
because they belong to same group

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.
