Zinc : Temperature
Zinc is a shiny and blue metal. When it is exposed to air it loses its shine. It can be melted on a cooking pan with a melting point of 419.53 °C and it has a low temperature for a metal. When it is boiled it emits zinc oxide, a gas that if breathed in, the lungs can struggle. Also when it gets heated it turns brittle and that makes it easy to be formed into an alloy.

What molecules can zinc make?
Zinc is a very reactive metal. It can combine with oxygen to make zinc oxide which is a white powder used for skin. The formula is (ZnO). Zinc is a chalcophile. A chalcophile is a chemical that would like to mix with sulfur more than oxygen. Some react with oxygen. And some metals react with sulfide. Zinc is a chalcophile because it can be found commonly as zinc sulfide but not zinc oxide. Chalcophiles like ores and are happy mixing with sulfide. Zinc sulfide can be used for pigments of plastic, rubber, and paint. The formula for zinc sulfide is (ZnS).

The Origin and discovery of zinc
 According to the Royal Society of Chemistry “The name is derived from the German, 'zinc', which may, in turn, be derived from the Persian word 'sing', meaning stone.” Andreas Sigismund Marggraf discovered zinc. He was not the first but he was the first to explain the process of extracting zinc. He heated calamine and carbon in 1746 to isolate zinc. According to Merriam Webster, isolating an object means “to separate from another substance so as to obtain pure or in a free state”
