A nonpolar covalent bond is a type of chemical bond where two atoms share electrons equally. This usually happens between atoms of the same element, like two hydrogen atoms or two oxygen atoms. Because the atoms have the same electronegativity, they pull on the shared electrons with equal strength, resulting in a balanced distribution of charge. In nonpolar molecules, such as methane (CH₄) or carbon dioxide (CO₂), the lack of charge separation means they do not have distinct positive or negative ends. This property makes nonpolar substances generally insoluble in water, which is a polar solvent, and influences their behavior in chemical reactions.
