![]() ![]() The key difference between ruthenium and rhodium is that ruthenium contains seven electrons in the outermost d electron shell whereas rhodium contains eight electrons in the outermost d electron shell. The key difference between ruthenium and rhodium is that ruthenium contains seven electrons in the outermost d electron shell whereas rhodium contains eight electrons in the outermost d electron shell.īelow table presents a detailed comparison of both elements to discern the difference between ruthenium and rhodium.īoth ruthenium and rhodium are in the same period in the periodic table of elements, but they are in different groups because they have different atomic numbers. Ruthenium is a chemical element having the atomic number 44 while rhodium is a chemical element having the atomic number 45. What is the Difference Between Ruthenium and Rhodium? Upon solidification, this absorbed oxygen is completely released. It can absorb oxygen only at the letting point of the metal. Normally, it does not form oxides even upon heating. Rhodium is a hard metal having a high reflectance. ![]() The melting point and boiling point are very high (about 19 Celsius, respectively). This metal is paramagnetic because it has unpaired electrons. When considering the natural occurrence of rhodium, it is primordial, and in its solid-state, rhodium has a face-centered cubic crystal structure. The most common oxidation state of rhodium is +3. Sometimes it occurs as an alloy with similar metals, and it rarely occurs as a chemical compound in minerals. Ruthenium vs iridium free#We can find this metal naturally as a free metal due to its inert nature. There is only one naturally occurring isotope of rhodium (Rh-103). ![]() Therefore, we can classify it as a noble metal. It is a hard metal that is corrosion-resistant and chemically inert. Rhodium appears as a silvery-white metal. It is a rare transition metal that is in group 9 and period 5 of the periodic table of elements. The chemical symbol of this element is Rh. Rhodium is a chemical element having the atomic number 45. In addition to that, ruthenium has only one electron in the outermost electron shell whereas all other group 8 elements contain two electrons. Moreover, ruthenium contains unpaired electrons, which makes it paramagnetic. The crystal structure of the solid ruthenium is a hexagonal close-packed structure. This solid substance appears as a polyvalent hard white metal. Ruthenium naturally occurs in its primordial state. The most common and stable oxidation states of ruthenium are +3 and +4. At room temperature and pressure, this chemical element occurs in the solid state and it has a very high melting point (about 2300 Celsius) and a very high boiling point (about 4400 Celsius). ![]() Therefore, it is a d block element, and the electronic configuration of this element is 4d 75s 1. We can find ruthenium in group 8 and period 5 of the periodic table of elements. The chemical symbol for ruthenium is Ru, and it is a rare transition metal. Ruthenium is a chemical element having the atomic number 44. Side by Side Comparison – Ruthenium vs Rhodium in Tabular Form But they have different atomic numbers therefore, these chemical elements have different chemical and physical properties as described below. The key difference between ruthenium and rhodium is that ruthenium contains seven electrons in the outermost d electron shell whereas rhodium contains eight electrons in the outermost d electron shell.īoth ruthenium and rhodium are chemical elements in period 5 of the periodic table. ![]()
