Chemical changes are . changes in the arrangements and connections between ions and atoms, and a change in chemical properties.. Ionic compounds can form from transition metals. Transition metals do not always follow the patterns that we discussed. Can have more than one oxidation number (charge. ). To identify the charges of transition metals, roman numerals are placed in their name, directly after the transition metal. . 1. Describing a Chemical Reaction.
