Question

Which electron dot diagram best represents a compound that contains both ionic and covalent bonds?

Answer 1

Step-by-step explanation:

To represent a compound with both ionic and covalent characteristics, you can use Lewis electron dot diagrams. In these diagrams:

For ionic bonds, you show the transfer of electrons from one atom to another, resulting in the formation of ions. For example, if you have sodium (Na) and chlorine (Cl) forming an ionic bond, you'd represent it as Na⁺ and Cl⁻.For covalent bonds, you show the sharing of electrons between atoms. In polar covalent bonds, one atom will have a partial negative charge (δ-) while the other has a partial positive charge (δ+). For example, in hydrogen chloride (HCl), you'd represent it as H(δ+)—Cl(δ-).

To show a compound with both types of bonds, create a diagram that illustrates the individual bonds within the compound. For instance, a compound like sodium chloride (NaCl) contains both ionic and polar covalent characteristics, so you'd show the transfer of electrons between Na and Cl (ionic) and the unequal sharing of electrons between H and Cl (polar covalent).

Answer 2

The electron dot diagram for a compound with both ionic and covalent bonds shows the transfer of electrons between atoms, as well as the sharing of electrons between nonmetal atoms.

Step-by-step explanation:

An electron dot diagram represents the valence electrons in an atom or molecule. In a compound with both ionic and covalent bonds, the electron dot diagram will show the transfer of electrons from the metal atom to the nonmetal atom, as well as the sharing of electrons between the nonmetal atoms.

For example, consider the compound sodium chloride (NaCl), which contains both ionic and covalent bonds. The electron dot diagram for NaCl would show the transfer of one electron from sodium (Na) to chlorine (Cl), creating Na+ and Cl- ions. The Cl- ions can then form covalent bonds with other Cl- ions.

Another example is water (H2O), where the electron dot diagram shows the sharing of electrons between the oxygen (O) atom and the two hydrogen (H) atoms.
