 * Zinc



=**symbol is Zn **= =**Atomic number is 30 **= =** Protons: 30 **= =** Reactions **= = = ** Cost of zinc ** = =
 * =** Neutrons: 35 **=
 * =** Electrons:30 **=
 * =** Melting point 419.53 degrees Celsius **=
 * =** Boiling point: 907 degrees Celsius **=
 * =**Atomic mass: 65.39 **=
 * ** Density: 7.134 g/cm3 **
 * ** Element classification is metal **
 * ** how it was discovered: **
 * =**Metallic zinc was first discovered in India in the 1400s by heating the mineral calamine with wool. **=
 * =** Zinc was rediscovered by Andres Sigismund Marggraf in the 1764 by heating calamine with charcoal. **=
 * =** Today, most zinc is produced through the electrolysis of aqueous zinc sulfate. **=
 * =** One third of all metallic zinc produced today is used in a process as galvanization. **=
 * =** How it is produced is during galvanization an object that is a subject to corrosion such as iron nail is given a protective layer of zinc. **=
 * =** Valence electrons are +2 **=
 * =** Zinc is added to a solution of iodine in ethanol. An exothermic redox reaction occurs. Zinc metal tarnishes in moist air. Zinc burns in air to form white zinc (ll) oxide. **=
 * =** Zinc price is $3.70 pre 100 grams **=
