1. Who discovered Ruthenium?1844
2. What is the scientific name?Ruthenium
3. What is the element symbol?Ru
4. What is ruthenium and why is it special?Ruthenium is a rare, shiny metal that is very hard and almost never rusts. It belongs to the platinum group and is used in electronics and as a catalyst.
