Chemical behaviour of Actinides

Actinides are strong reducing agent and very reactive in crushed from. They are radioactive due to less stable nuclei and also have no stable isotopes. They have variable oxidation state due to which its study is quite difficult –

  • They readily react with HCl but when they react with nitric acid, a small effect appears due to the formation of oxide layer on their surface.
  • Actinides form oxide and hydride, when react with boiling water.
  • They do not react with alkali metals.
  • At moderate temperature, they combine with non-metals.

    Actinides are those elements in which 5f subshell is gradually filled from actinium to lawrencium. The Actinides series contains consecutive 14 elements from atomic number 89 to 103, from actinium to lawrencium, called Actinides.They are called Actinides because they start immediately after acitinium, the first elements of this series.They are…

    The f –block elements are those in which atoms or ions have valence electrons  in f-orbital. They are also called inner transition elements because the last or valence electron enters in (n-2)f orbital means in anti-penultimate energy level. They are also referred as rare earth elements. The general electronic configuration…

    Atomic and ionic size – As the atomic number increases, the atomic size increases and  effective nuclear charge also increases which attracts the outermost shell more effectively. So, as we move left to right means from actinium to lawrencium in the actinide series, there is gradual decrease in the the…

    In lanthanides series, first few elements are quite reactive with calcium but with increase in atomic number, their reactivity is quite similar to aluminum. Lanthanides when reacted with carbon in inert atmosphere, then there is the formation of carbides.On gentle heating, it combine with hydrogen. Lanthanides form halides in the…
