In chemistry, a polar bond is a type of covalent bond between two atoms or more in which electrons are shared unequally. Because of this, one end of the molecule has a slight, relative negative charge and the other a slight, relative positive charge. An example of atoms bonded by a polar bond is the water molecule, which is made up of two hydrogen atoms and one oxygen atom.

“In time your relatives will come to accept the idea that a career is as important to you as your family. Of course, in time the polar ice cap will melt.”

“When the bond of love broke,
the respect born of affection withered,
good feelings fled,
and that man walked before me
like any other,
Good Friend,
I imagine all this,
think on days gone by
and wonder why
my heart hasn’t cracked
into a hundred bits.”
—Amaru (c. seventh century A.D.)
