Rhodium properties
The transition metals, also called transition elements, is the group to which rhodium belongs. In this group of chemical elements to which rhodium belongs, there are those located in the central part of the periodic table, specifically in block d. Among the characteristics that rhodium has, as well as those of the rest of the transition metals, is that of including the d orbital, partially filled with electrons, in its electronic configuration. Properties of this type of metal, among which rhodium is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of rhodium in its natural form is solid. Rhodium is a metallic silver-white chemical element and belongs to the group of transition metals. The atomic number of rhodium is 45. The chemical symbol for rhodium is Rh. The melting point of rhodium is 2237 degrees Kelvin or 1964.85 degrees Celsius or degrees Celsius. The boiling point of rhodium is 3968 degrees Kelvin or 3695.85 degrees Celsius or degrees centigrade.
Atomic properties of rhodium
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element.
