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
Various isolated examples of the use of impure zinc in ancient times have been discovered. Zinc ores were used to make the zinc–copper alloy brass thousands of years prior to the discovery of zinc as a separate element. Judean brass from the 14th to 10th centuries BC contains 23% zinc.
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.

Zinc [SEP] Ancient use
Various isolated examples of the use of impure zinc in ancient times have been discovered. Zinc ores were used to make the zinc–copper alloy brass thousands of years prior to the discovery of zinc as a separate element. Judean brass from the 14th to 10th centuries BC contains 23% zinc. Knowledge of how to produce brass spread to Ancient Greece by the 7th century BC, but few varieties were made. Ornaments made of alloys containing 80–90% zinc, with lead, iron, antimony, and other metals making up the remainder, have been found that are 2,500 years old. A possibly prehistoric statuette containing 87.5% zinc was found in a Dacian archaeological site.
