The elements of group 13 have the general configuration ns 2 np 1 (one electron in the outermost p-orbitals and two electrons in the s-orbital). Their electronic configurations are given in the below tab..

The elements of group 14 have four electrons in the outermost orbitals. The general configuration may be written as ns 2 np 2 (one electron in the outermost p-orbitals and two electrons in the s-orbital..

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' represents the valence sh..

Hydrogen atom has one electron in its valence shell like alkali metal..

Like halogens, hydrogen has only one electron less than the nearest noble gas configuration. H : 1s 1 He : 1s 2 F : 1s 1 2s 2 2p 5 Ne : 1s 1 2s 2 2p ..

Electronic Configuration - The distribution of electrons in different orbitals is known as its electronic configuration. This characterizes each electron in an atom. The electronic configuration is expressed by indicati..

The general electronic configuration of d-block elements is (n-1) d 1-10 ns 1-2 . All the d-block elements except zinc, cadmium and mercury have partially filled d-orbitals. But, zinc, cadmium and mercury have completely filled d-orbitals and they e..
