Group 2 elements are called alkaline Earth metals. These elements have two electrons in the valence shell of their atoms, preceded by the noble gas configuration. Their general configuration is written as [Noble gas] ns 2 where 'n' repre..

The last electron enters into 5f-orbital in these elements. The electronic configuration of actinides is given below. The general electronic configuration of these elements is 5f 1 - 1 4 6d 0 - 1 7s 2 . ..

The arrangement of electrons in the various shells/orbits/energy levels of an atom of the element is known as electronic configuration. Keeping the Bohr and Bury rules in mind let us write the electronic configuration of elements..
