Those at increased risk include: 1  People with diabetes. 2  People with high blood pressure. 3  People with a family history of kidney failure. 4  People who are 65 years or older. 5  Certain ethnic groups including African Americans, Hispanics, Asians, American Indians.
The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
Polar molecules occur when two atoms do not share electrons equally in a covalent bond. A dipole forms, with part of the molecule carrying a slight positive charge and the other part carrying a slight negative charge. This happens when there is a difference between the electronegativity of each atom.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.
