Concept Introduction:

Elements with same valence electrons are placed in the same group in periodic table

Chemical properties of an element can be determined by the number of electrons in the subshell containing the outermost electrons.

The elements with same number of valence electrons have similar physical and chemical properties.

Representative elements contain either s or p subshell which are incomplete and have outer electronic configurations of ns(1-2)np(0−5)

During a particular reaction alkali metals and alkaline earth metals forms a cation having the same number of electrons as the noble gas that precedes it

Electron configuration is the distribution of electrons in the atomic orbitals. It gives an idea about the shape and energy of electrons in an atom.
