Properties of osmium
The transition metals, also called transition elements, is the group to which osmium belongs. In this group of chemical elements to which osmium belongs, are those located in the central part of the periodic table, specifically in block d. Among the characteristics that osmium has, as well as those of the rest of transition metals, is that of including in its electronic configuration the d orbital, partially filled with electrons. Properties of this type of metal, among which osmium is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of osmium in its natural form is solid. Osmium is a grayish-blue chemical element and belongs to the group of transition metals. The atomic number of osmium is 76. The chemical symbol for osmium is Os. Osmium’s melting point is 3306 degrees Kelvin or 3033.85 degrees Celsius or degrees Celsius. The boiling point of osmium is 5285 degrees Kelvin or 5012.85 degrees Celsius or degrees Celsius.
