• Element: An element is a pure substance that cannot be made simpler by chemical means. Cerium is one of these elements.
• Ductile: This means that Cerium can be stretched or shaped easily without breaking.
• Grey Metallic: Cerium is a shiny, silver-grey metal.
• Lanthanide Series: This is a group of 15 elements in the periodic table that have similar properties. Cerium is one of these elements.
• Rare-earth Group: Cerium is considered a rare-earth metal, meaning it is part of a group of elements that are not commonly found in large amounts in the Earth.
