They are all shiny, relatively reactive metals. Those that follow Actinium (Ac) are called actinides. They are all radioactive metals. This means they are unstable. They break down into different, more stable elements. You can read more about radioactive elements in the chapter Nuclear Chemistry . Many of the actinides do not occur in nature but are made in laboratories. Q: What do you call the metal elements listed below the periodic table? Choices: - rare metals - shift metals - process metals - transition metals A:
The answer to this question is:
