Cadmium properties
The transition metals, also called transition elements, is the group to which cadmium belongs. In this group of chemical elements to which cadmium belongs, are those located in the central part of the periodic table, specifically in block d. Among the characteristics that cadmium 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 cadmium is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of cadmium in its natural form is solid. Cadmium is a silver-gray metallic chemical element and belongs to the group of transition metals. The atomic number of cadmium is 48. The chemical symbol for cadmium is Cd. The melting point of cadmium is 594.22 degrees Kelvin or 322.07 degrees Celsius, or degrees Celsius. The boiling point of cadmium is 1,041 degrees Kelvin or 768.85 degrees Celsius or degrees Centigrade.
Atomic Properties of Cadmium
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.
