Use ideas about electronic structure to explain why the noble gases are unreactive.

the nobel gases are unreactive bcz it alredy has stable electronic configuration due to which it neither donate nor receive electrons during the chemical reaction so ,it is are unreactive..

Noble gases are nonreactive because their duplet and octet is complete. They no more need any electron to complete their duplet or octet. Elements are usually reactive because they tend to lose and gain electrons and Since noble gases have no tendency to gain or lose electrons, They are inert, noble and nonreactive.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
