The elements in which the differentiating electron enters the penultimate energy level i.e. (n−2)f, are called f-block elements. Due to such electronic configuration where the last electron enters the ...

The lanthanide (4f) and actinide (5f) elements (collectively the “f-block”) comprise around a quarter of the periodic table, and many are essential to key aspects of modern life and society. These ...

Now, solving the NCERT Exemplar problems becomes quite easy with the help of the solutions provided at jagranjosh.com/cbse, as these solutions will help you get a ...

One of the greatest challenges facing the future of clean nuclear energy is scientists’ ability to recover heavy metals from nuclear waste, such as lanthanides and actinides. A new computational tool ...

It’s difficult to make molecules using elements that lie beyond uranium on the periodic table, which has hampered progress in studying how actinides form bonds. Now chemists have expanded the library ...

RUN your fingers over the white keys of a piano. The notes get higher and higher as your hand moves to the right. On the eighth key, something beautiful happens: a note hangs in the air that embodies ...

University of Hull provides funding as a member of The Conversation UK. But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements. Decades before, ...
