A table of alchemical symbols from Basil Valentine's The Last Will and Testament, 1670 Alchemical symbols before Lavoisier Alchemical symbols were used to denote chemical elements and compounds, as well as alchemical apparatus and processes, until the 18th century.
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon).
Many more symbols were in at least sporadic use: one early 17th-century alchemical manuscript lists 22 symbols for mercury alone. [10] Planetary names and symbols for the metals – the seven planets and seven metals known since Classical times in Europe and the Mideast – was ubiquitous in alchemy.

Chalk – a rock composed of porous biogenic calcium carbonate. CaCO 3; Chrome green – chromic oxide and cobalt oxide.
The word "chalcogen" is derived from a combination of the Greek word khalkos (χαλκός) principally meaning copper (the term was also used for bronze, brass, any metal in the poetic sense, ore and coin), [3] and the Latinized Greek word genēs, meaning born or produced. [4] [5]
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
