Answer:
Step-by-step explanation:
Polar covalent bonds and nonpolar covalent bonds are similar in that they both involve the sharing of electrons between atoms in a covalent bond. In both types of bonds, the atoms involved share electrons in order to achieve a full valence electron shell, which gives the bond its stability.
Both polar and nonpolar covalent bonds have a covalent character, meaning they are formed by the sharing of electrons between atoms, as opposed to the transfer of electrons which is seen in ionic bonds. Also, both type of bonds are strong chemical bonds, which means they have a high bond energy, meaning they require a lot of energy to break.
