Zn: This stands for Zinc, used in galvanization to prevent rusting. Ga: This is the symbol for Gallium, used in semiconductors and LEDs. Ge: Represents Germanium, important in fiber optics and infrared optics. As: This is the symbo...
Notice that there are several places in the table that have no chemical symbol, but are instead labeled with a question mark. Between zinc (Zn) and arsenic (As) are two such missing elements. Mendeleev believed that elements with atomic masses of 68 and 70 would eventually be discovered and...

PERIODIC TALES: A CULTURAL HISTORY OF THE ELEMENTS, FROM ARSENIC TO ZINC offers a lively history of the elements from an author or decided to construct how own periodic table, collecting samples of the elements and revealing stories behind each of them. Periodic Tales SCIENTISTS have written what...
The filling of the shell n=3 is interrupted at Z=19 (potassium, third alkali element) because the level 4s is lower in energy than the 3d level that starts to be filled after the 4s from scandium (Z=21) to zinc (Z=30). There is a competition between the levels 4s and 3d that ...
The one I got is tungsten metal (not tungsten carbide), and the tip is zinc alloy, basically a windshield that makes the shape more aerodynamic while permitting the tungsten core to have the optimal penetrating shape. (Analysis by x-ray fluorescence spectroscopy at the Center for Microanalysis ...
