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.
Ionic is when one of the elements is a metal. Covalent is when both are nonmetals. Lithium is a metal so LiOH is an ionic compound.ovalent compounds are generally more soluble in organic solvents than in â¦ water, have a low melting point and do not conduct electricity well in water. Ionic compounds are formed when one or more electron are transferred from one atom to another. They stick together like magnets attract to each other.
