Gold properties

The transition metals, also called transition elements, is the group to which gold belongs. In this group of chemical elements to which gold belongs, are those located in the central part of the periodic table, specifically in block d. Among the characteristics that gold 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 gold is found, are its high hardness, high boiling and melting points, and good conductors of electricity and heat.

The state of gold in its natural form is solid. Gold is a chemical element with a metallic yellow appearance and belongs to the group of transition metals. The atomic number for gold is 79. The chemical symbol for gold is Au. The melting point of gold is 1337.33 degrees Kelvin or 1065.18 degrees Celsius or degrees Celsius. The boiling point of gold is 3129 degrees Kelvin or 2856.85 degrees Celsius or degrees centigrade.

Atomic properties of gold

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 the position where to find gold within the periodic table of elements, gold is in group 11 and period 6. Gold has an atomic mass of 196.966569 u.

The electron configuration of gold is [Xe] 4f145d106s1. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. Gold’s mean radius is 135 pm, its atomic radius or Bohr radius is 174 pm, its covalent radius is 144 pm, and its Van der Waals radius is 166 pm. Gold has a total of 79 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, 32 electrons, in the fifth shell it has 18 electrons and in the sixth, 1 electron.
