What is the Difference Between Ruthenium and Rhodium?

Ruthenium and rhodium are both transition metals located in period 5 of the periodic table of elements. Despite their similarities, they have distinct differences in their chemical properties and uses.

Rhodium:

• Atomic number: 45
• Symbol: Rh
• Group in the periodic table: Group 9
• Family in the periodic table: Cobalt family
• Electronic configuration: [Kr] 4d8 5s1
• Melting point: 2237 K
• Boiling point: 3968 K
• Uses: Mainly used in catalytic converters for cars, as it reduces nitrogen oxides. It is also used as an industrial catalyst for nitric acid, acetic acid, hydrogenation reactions, etc.

Ruthenium:

• Atomic number: 44
• Symbol: Ru
• Group in the periodic table: Group 8
• Family in the periodic table: Iron family
• Electronic configuration: [Kr] 4d7 5s1
• Melting point: 2607 K
