Chemistry is fascinating, and there are many interesting facts about elements and compounds. Compounds can be polar, nonpolar, or ionic, and they each have unique properties. Polar compounds have an uneven distribution of electrons across their geometry, resulting in a dipole, while nonpolar compounds are perfectly balanced and strongly bonded. Scientists and chemists use the properties of polar and nonpolar compounds for separation, mixing, and creating new compounds.
Polarity is important because it determines whether a molecule is hydrophilic or hydrophobic. Molecules with high polarity are hydrophilic and mix well with other polar compounds like water. In contrast, nonpolar molecules like oils are hydrophobic and are not attracted to water molecules. To determine the polarity of a covalent bond, find the difference between the electronegativity of the atoms. If the result is between 0.4 and 1.7, the bond is generally polar covalent. Nonpolar covalent bonds are very strong, requiring a large amount of energy to break the bond. They are essential in biology, forming the oxygen we breathe and making up our living cells.
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule.
Elements contain one type of element like carbon, oxygen is usually non-polar

Usually, compounds containing carbon and hydrogen only like ethane, and methane are automatically nonpolar.
Oils, by contrast, are nonpolar, and as a result, they're not attracted to the polarity of water molecules. Oils are hydrophobic, or "water fearing." Instead of being attracted to water molecules, oil molecules are repelled by them
Ionic compounds are composed of positively charged cations and negatively charged anions, held together by electrostatic forces. They usually form crystalline structures when solid and can be produced from their constituent ions by evaporation, precipitation, freezing, or electron transfer reactions.
