Question:
The pair of elements that has similar atomic radii is}
The pair of elements that has similar atomic radii is}
Show Hint
Because of lanthanide contraction, second and third transition series elements of the same group often have very similar sizes.
Updated On: Apr 24, 2026
- Mo and W
- Ti and La
- Ag and Ni
- Mn and Os
- V and W
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Molybdenum (Mo) and tungsten (W) belong to the same group.
Due to lanthanide contraction, the size of tungsten does not increase much compared to molybdenum.
So their atomic radii become very similar.
Hence, the correct answer is: \[ \boxed{(A)\ \text{Mo and W}} \]
Hence, the correct answer is: \[ \boxed{(A)\ \text{Mo and W}} \]
