Comprehensive data on the chemical element Zinc is provided on this page; including scores of properties, element names in many languages, most known nuclides of Zinc. Common chemical compounds are also provided for many elements. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies.

Number of fats was found to be 5.6 (Spiers, 1946), 6.0 (Rutherford et aI., 1976) and 5.95 (White, 1977). The higher effective atomic number offats compared with that of pure rubber is possibly due to the presence of oxygen. CONCLUSION The effective atomic number of rubber has been measured using a collimated gamma ray transmission method. To find the number of protons in zinc zinc, first locate the element on the periodic table. Next, find the atomic number which is located above the element 's symbol. Since zinc zinc 's atomic number is 30 30, Zn Zn has 30 30 protons. The atomic number of zinc (Zn) is 30. The atomic weight of Zn is 65.39 grams per mole.
