zIllustrate by taking examples of transition elements and non-transition elements that oxidation states of elements are largely based on lectronic configuration.

Oxidation state of an element, depends upon the electrons present in the outermost shell or eight minus the number of valence shell electrons (outernost shell electrons) .
Alkali metals (Group 1 elements) General valence shell electronic configuration - ns1;
oxidation state = +1.
Alkallne earth metals( Group 2 elements ) General valence shell electronic configuration - ns2 oxidation state = +2
Alkali metals and alkaline earth metalks belong to s - block elements and elements of group 13 to group 18 are known as p - block elements.
Group 13 elements General valence shell electronic configuration −ns2np1 Oxidation
States = +3 and +1
Group 14 element General valence shell electronic configuration - ns2np2; Oxidation states =+4and+2.
Group 15 elements General valence shell electronic configuration ns^2 np^3; Oxidation
States =−3+3and+5, Nitrogen shows+1,+2,+4 oxidation states also,
Group 16 elements
General valence shell electronic configuration −ns2np4 oxidation staes =−2,+2,+4and+6
Group 17 elements General valence shell electronic configuration - ns^2 np^6; Oxidation states = - 1, Cl Br and I also show +1, 3, +5 and +7 oxidation states,
Group 18 elements
General valence shell configuration −ns2np6. Oxidation states = zero.
Transition elements or d - lock elements General electronic configuration - (n−1)d1−10ns1−2 . these elements show variable oxidation states due to involvement of not only ns electrons but d or f - electrons (inner - transition elements) as well . Their most common oxidation states are +2 and +3
