A plough or plow (US; both / p l aÊ /) is a tool or farm implement used in farming for initial cultivation of soil in preparation for sowing seed or planting to loosen or turn the soil. Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors.
Nonpolar molecule. Definition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.However, the polar bonds in nonpolar molecules are arranged symmetrically causing dipoles to cancel out each other. As a result, nonpolar molecules have no net dipole.efinition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.
Some molecules are clearly polar or nonpolar, while many have some polarity and fall somewhere in between. Here's a look at what polar and nonpolar mean, how to predict whether a molecule will be one or the other, and examples of representative compounds.ou can predict nonpolar molecules will form when atoms have the same or similar electronegativity. Examples of nonpolar molecules include: 1  any of the noble gases: He, Ne, Ar, Kr, Xe. 2  any of the homonuclear diatomic elements: H 2, N 2, O 2, Cl 2.
