1. Show the class pictures of five very different mammals, such as a cat, kangaroo, horse, rabbit, and monkey. Explain that all these animals are mammals, and that mammals constitute one class of the animal kingdom, which also includes other classes, such as reptiles, birds, and fish. Ask students what these five mammals have in common and mark their responses on a sheet of chart paper.
When ionic compounds are in a molten state or dissolved in water, forming an aqueous solution, the ions that formed the ionic compounds are able to move around freely, thus able to conduct electricity.
Report Abuse. As ionic compounds, Na and Cl transferred electrons to bond. NaCl can only conduct electricity if it is melted or diluted in water. When diluted in water, the polar nature of the water breaks up the electromagnetic charges that hold NaCl together, thus making the solution able to pass electrons.aCl can only conduct electricity if it is melted or diluted in water.
