About the Element Element name: Zinc Atomic number: 30 Atomic Mass: 65.4 Protons: 30 Neutrons: 35.4 Electrons: 30 Group: 12 Period: 4 Zinc is one of the most common and useful elements on the periodic tablle. Long ago it was used as an ore, now days it is used as a cleaning product, in dry cell batteries, dietary suppliment, and even in sports drinks. Zinc is an incredible element that will be used and newly discovered in the future as one of the most beneficial eleemeents on earth. About the Element	Isotope Table Isotope ........

History Zinc has been around for hundreds of years, It's handy uses and conveniant placement around the world have been a great and easy shortcut to have a more zinc-quenched eatrh. It was first produced in the 13th century in India, later discovered in Germany given the name Zin, and then rediscovered in Europe by Andreas Marggraf and used as ores until it was found to be an elemenore atoms having the same atomic number but different mass numbers.
