where was this element first isolated?
In India by 1300 AD.
Zinc
Metallic zinc was isolated in India by 1300 AD, much earlier than in the West. Before it was isolated in Europe, it was imported from India in about 1600 CE
where is zinc located on the periodic table It is the first element in group 12 of the periodic table. what is this element? Zinc how is the above described? Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. what is the table mentioned previously? The periodic table what is the purpose of this table? The organization of the periodic table can be used to derive relationships between the various element properties, and also to predict chemical properties and behaviours of undiscovered or newly synthesized elements. what are the physical properties of the element? Zinc is a bluish-white, lustrous, diamagnetic metal, which is less dense than iron and has a hexagonal crystal structure and is hard and brittle at most temperatures. in what form does the element occure on earth's atmosphere? Zinc is found in the Earth's crust in soil and also in seawater. are they found in forms of ores? Yes - The element is normally found in association with other base metals such as copper and lead in ores. what are the isotopes of this element? Five stable isotopes of zinc occur in nature, with Zn being the most abundant isotope (49.17% natural abundance). The other isotopes found in nature are (27.73%), (4.04%), (18.45%), and (0.61%). how does this element react? It is a moderately reactive metal. how does it react when exposed to air? Zinc burns in air with a bright bluish-green flame. how are they used in ancient period? Zinc ores were used to make the zinc–copper alloy brass thousands of years prior to the discovery of zinc.

Zinc [SEP] Isolation
Metallic zinc was isolated in India by 1300 AD, much earlier than in the West. Before it was isolated in Europe, it was imported from India in about 1600 CE. Postlewayt's "Universal Dictionary", a contemporary source giving technological information in Europe, did not mention zinc before 1751 but the element was studied before then. Flemish metallurgist and alchemist P. M. de Respour reported that he had extracted metallic zinc from zinc oxide in 1668. By the start of the 18th century, Étienne François Geoffroy described how zinc oxide condenses as yellow crystals on bars of iron placed above zinc ore that is being smelted.
