d - block and f - block Elements
Separation of lanthanides from their mixture is not easy because of:
The separation of Lanthanoid elements is difficult. Explain.
This is due to lanthanide contraction. As the change in atomic radii is very small so they possess almost similar chemical properties. That's why the separation is difficult.
Separation of lanthanides from their mixture is not easy because of:
Which of the following statements is not correct?
What is the expression for the covalent radius of the following? Zr _____ Hf
Reason of lanthanoid contraction is:
The extent of actinoid contraction is greater than lanthanoid contraction explain.
The pair that has similar atomic radii is :
Because of lanthanoid contraction, which of the following pairs of elements have nearly the same atomic radii?
The most basic hydroxide from following is?
What is meant by lanthanoid contraction? The actinoid contraction is grater than that of lanthanoid contraction. Why ?
Which of the following factor may be regarded as the main cause of lanthanide contradiction?
