Question

Study of actinide elements is difficult.Give 2 reasons

Answer 1

Study of actinoids is more complicated beacuse..

• actinoids shows greater no. of oxidation states due to the comparable energies of 5f,6d and 7s orbitals

• most of the actinoids are radioactive and the study of their chemistry in the lab is difficult...

    hope it would help u

Answer 2

Actinoid elements are the elements in which the last electrons enter the 5f orbital.

From the atomic number, 90-103 are the actinide elements.

They also include the 11 transuranic elements from the periodic table.

The study of the actinide elements is difficult because:

• The actinide elements are mostly radioactive elements. Their half-lives are relatively short, making them difficult to study.
• The actinoid elements can usually be prepared in small quantities like in nanograms.

Hence, the study of actinoid elements is difficult.
