On this page you can discover the chemical properties of erbium and information about erbium and other elements of the periodic table such as thorium, protactinium, neptunium or plutonium. You will also learn what erbium is for and you will know its uses through its properties associated with erbium such as its atomic number or the usual state in which erbium can be found.

You will be able to see qualities of erbium such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in erbium atoms and other properties.

For some elements, part of this information is unknown. In these cases we show the properties attributed to them.

Erbium properties

Erbium is part of the lanthanide group. Lanthanides are also called rare earths since they are commonly presented as oxides. Together with the actinides, the lanthanides form the internal transition elements.

The state of erbium in its natural form is solid. Erbium is a silvery-white chemical element and belongs to the group of lanthanides. The atomic number of erbium is 68. The chemical symbol for erbium is Er. Erbium’s melting point is 1795 degrees Kelvin or 1522.85 degrees Celsius, or degrees Celsius. The boiling point of erbium is 3136 degrees Kelvin or 2863.85 degrees Celsius or degrees Centigrade.

Atomic properties of erbium

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. Regarding its position within the periodic table of elements, it can be found in period 6. Erbium has an atomic mass of 167,259 u.

The electron configuration of erbium is [Xe] 6s24f12. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. Erbium’s mean radius is 175 pm and its atomic radius or Bohr radius is 226 pm. Erbium has a total of 68 electrons whose distribution is as follows: In the first shell it has 2 electrons, in the second it has 8 electrons, in its third shell it has 18 electrons, in the fourth, 30 electrons, in the fifth shell it has 8 electrons and in the sixth, 2 electrons.
