When they are circumscribed by an Arctic Circle.
CO2 is a polar molecule because it has a symmetrical linear shape that results in unequal distribution of charge. The other molecules listed are nonpolar because they have symmetrical shapes that result in an even distribution of charge.
if the molecule is symmetrical, then it is nonpolar. if it is NOT symmetrical, it is polar. Ionic bonds form between a metal and a nonmetal.
no
Yes.
there is a lot like irregular shapes
You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
A snitch and the deathly hallows symbol are both symmetrical shapes.
Where it has to do with symmetrical shapes and there equations.
Symmetrical
Perchloroethylene (perc) is a non-polar molecule due to its symmetrical structure and lack of polar bonds.
symmetrical shapes
Yes because they are 'mirror images'
