Long before chemists knew the formulas for chemical compounds, they developed a system of nomenclature that gave each compound a unique name today we often use chemical formulas, such as nacl, c 12 h 22 o 11, and co(nh 3) 6 (clo 4) 3, to describe chemical compounds.
In chemistry, the concept of polarity refers to how some chemical bonds result in unequal sharing of electrons this means shared electrons will be closer to one atom in a bond than another, which creates areas of positive and negative charge.
