How do water molecules act like little magnets?

Best Answers

Water molecules are basically, #H_2O# molecules, which have bent shapes. Also, #O# atom is electronegative than #H# atom. So, the entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each #O-H# bonds, and thus, the water molecules are polar in nature and act like"little magnets". read more

Just like opposite magnetic poles attract and similar poles repel, so do atoms. What really makes this occurrence special is the force that water molecules exert on one another, hence acting like little magnets. read more

An attractive force that holds molecules of a single substance together. Cohesion produces _____ tensions as the water molecules hold tightly together. Surface. read more

Water molecules bond with each other through hydrogen bonding. This type of bonding is a strong one as compared to other intermolecular forces present. The partial positive of the oxygen attracts the partial positive of the hydrogen so they bind to each other. In this way, they act as little magnets. read more
