Molecules made up of two or more elements are called compounds. Nitrogen (N2), hydrogen (H2), water (H2O), ammonia (NH3), chlorine (Cl2), fluorine (F2) are some of the examples of the compounds having covalent bonds. IV. For example, graphite has a relatively high electrical conductivity within the carbon planes, and diamond has the highest thermal conductivity of any known substance. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). SOLUTION. Whereas in general, a covalent solution does not contain any ions. Molecular compounds are soft and brittle, while ionic compounds are hard and brittle Can molecular compounds be electrolytes? Ionic compounds are more reactive than molecular compounds. A valence electron is an outer shell electron that is associated with an atom. An example of an ionic compound is Sodium Chloride, NaCl, in which Sodium (NA) is the cation and Chlorine (Cl) is the anion. Ionic. You mentioned heat transfer - heat is the transfer of the kinetic energy of atoms and molecules. answer choices . Original question %3E How does citric acid conduct electricity?

Hydrogen Chloride is a convalent compound and does not conduct electricity.However,hydrochloric acid is able to conduct electricity.Why is this so?Thks Neutral atoms and their associated ions have … Since molecular compounds are composed of neutral molecules, their electrical conductivity is generally quite poor, whether in the solid or liquid state. So typically, even though we think of ionic compounds or metallic compounds able to conduct electric current, there are some instances where covalently bonded molecular compounds can conduct electricity as well. While metallic substances make good conductors of electricity, non-metallic substances usually do not. answer choices . Millenium falcon is a compound made from 2 elements, Millenium (Mi) and falcon (Fa).
