WebA more or less stable grouping of two or more atoms held together by chemical bonds is called a molecule. The bonded atoms may be of the same element, as in the case of H2, which is called molecular hydrogen or hydrogen gas. When a molecule is made up of two or more atoms of different elements, it is called a chemical compound. Webis above 1.7, an electron has been transferred from one atom to the other, and the resulting ions form an ionic bond. Figure 3 Covalent bonds are polar when the electronegativity difference is > 0.4 and nonpolar when it is ≤ 0.4 (A) The bonds between oxygen and hydrogen (O-H) and between nitrogen and hydrogen (N-H) are examples of polar bonds.
