lanthanide series and actinide series

These are called second inner transition series. The elements in which the last electron enters one of the 5f-orbitals are called as actinides (or) 5f-block elements. They include the elements from actinium (Ac) to Lawrencium (Lr). All these elements are radioactive and th..

Fourteen elements that follow lanthanum called lanthanides and fourteen elements following actinium called actinides were not given proper places in Mendeleev's periodic tabl..

Some significant similarities and differences between lanthanides and actinides are observed. They are discussed bel..

If x is a real number such that |x|<1, then the series is called the logarithmic series. It can be proved mathematically that this logarithmic series has the sum equal to log(1 + x). If x is a real number such that |x|<1, then the series is called th..

This is also called as 5d series which corresponds the filling of 5d orbital. The first element of this series is lanthanum whose atomic number is 57 and includes 9 elements from hafnium whose atomic number is 72 to mercury whose atomic number is 8..
