Which statement describes how the binary ionic compound CaCl2 is named?

In a binary ionic compound, the metal is named first and keeps its element name, while the nonmetal is named second and its ending changes to -ide. In CaCl₂, calcium is the metal and chlorine becomes chloride, giving calcium chloride. Thus, the correct statement is that the nonmetal is named second and its ending is replaced with -ide.
