r s configurations

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 ..

All the alkali metals have one electron in their outermost 's' orbitals preceded by the noble gas configuration. Thus, the general configuration of alkali metals may be written as [Noble gas] ns 1 where 'n' represents the valence shell. The electronic configurat..

The atoms of group 15 have five electrons in the outermost shell, two in s and three in p sub-shell. The general electronic configuration of this group may be expressed as ns 2 np ..

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). Their electronic configurations are given in the in table bel..
