In order to assess the possibility of a shortage, it helps to look at availability estimates provided by the US Geological Society of more than 100 minerals and metals, including many of the metals key for low-carbon technologies. They are called the "inner transition metals." In general, representative metals lose all of the s and p valence electrons to form their stable ions. Most transition metals have 2 valence electrons. Heavy metals enter the surroundings by natural means and through human activities. Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. There is a more or less horizontal lower portion (the lower shelf) joined by a steep line to a more or less horizontal upper portion (the upper shelf). Stable ions of the representative metals are determined by how many s and p valence electrons can be removed. Let us now study the uses of these unique elements in some more detail. Transition metals are extremely versatile elements, which show potential for application in various fields such as medicine, construction, energy, etc., due to their properties of malleability and ductility. The transition temperature range is defined by the vertical line, − 50 °C to − 40 °C in this case. The elements are called "transition" metals because the English chemistry Charles Bury used the term in 1921 to describe the transition series of elements, which referred to the transition from an inner electron layer with a stable group of 8 electrons to one with 18 electrons or the transition from 18 electrons to 32.
