The polarity of the atoms is often a primary factor in how different atoms combine to create various substances and formmolecules. Examples of polar molecules include ethanol (C2H6O), hydrogen sulfide (H2S), sulfur dioxide (SO2), ammonia (NH3) and hydrochloric acid (HCl). By contrast, nonpola...

The polar radius is the distance from the middle to the surface along that axis. The polar radius of the planet is 6357 km and also the polar diameter is 12,714 km.The equatorial diameter of earth is about 12,756 km. The equatorial bulge is because o...
The Barents–Kara region is significantly affected by climate change, leading to the rapid degradation of habitats and the infiltration of new potential infectious agents dangerous to pagophilic species, particularly the polar bear (Ursus maritimus). For individuals captured in the Barents Sea and the...

Predicting Polar vs. Nonpolar Covalent Bonds Lesson Summary Frequently Asked Questions How can you tell if a covalent bond is polar or nonpolar? Covalent bonds that are polar have an unequal sharing of a pair of electrons. This would be determined by an electronegativity difference of the two ...

Therefore, it is not possible to pinpoint the exact location of an electron. London dispersion forces are the momentary forces that occur when the electrons concentrate towards one end of the atom. The sudden shift of electrons causes a temporary polarity, drawing other, temporarily polar atoms ...
