===Hi! I'm urBFF912 and I'm here to tell you all about the element zinc. There are many physical characteristics of zinc, a strong solid. It is a bluish- pale gray metal. Because it is a metal, it has all the characteristics most metals have including being malleable, which means it can be bended and formed although only when melted, ductile, because the bands holding the atoms together easily break, and a strong solid. It’s malleable from 100 to 150 degrees. Its’ melting point is 419.3 degrees Celsius. Its’ density is 7.14 g/cm3. Its’ alloys are brass, aluminum, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium, and sodium. Like all other metals, it’s a good conductor of electricity and heat. Zinc also has chemical characteristics. It’s a moderately reactiv **e metal. Zinc reacts with acids, alkalis and other non- metals.** === ===[| Zinc] is used in many things. Zinc or variations of zinc can be found in dietary supplements, **deodorant, anti- dandruff shampoo, luminescent paints, luminous dials, X- ray and TV screens, fluorescent lights, batteries, sunscreen, and lozenges. Here is a. Pennies used to be made of copper, but since 2001, they have been made primarily out of zinc. It’s used to create die castings, which are used a lot in the automobile, electrical, and hardware industries. A huge newly discovered use is that it’s a cure for diarrhea, and is used in third world countries, where diarrhea is a primary cause of death. It’s estimated that the death toll will decrease by 23%. It’s been used often throughout history. Greek and Romans used zinc to make bronze statuettes and artifacts. It was smelted and extracted in India during the 13th century. The Chinese learned these practices in the 17th century. Also, there was the huge use of brass in Ancient Rome and the Indus** ===

===Zinc was discovered in pure metallic form by German chemist **in 1746. However, it was most likely named by the alchemist Paracelsus in the 16th century. Germany had many scientists studying it and experimenting on it in the 18th century. Here is a. But it was used in Greek and Rome artifacts and in India there has been artifacts discovered that contain zinc that are 2500 years old. Zinc is also used to make brass. Brass was first created by accident by the Romans. Zinc was very hard to find to make it, but they found it in an ore called smithsonite that contained zinc carbonate. They used brass for helmets and coins. China, Germany, Holland and Sweden have booming brass industries. Brass was used frequently during the Industrial Revolution. There are large deposits of zinc in Australia, Canada and the United States with the largest in Iran. Zinc makes up 0.0075% of the Earth’s crust. It’s also found in minerals and your own body. It’s readily available commercially and therefore not necessary to create in a lab.** ===

===Zinc is not a “happy” atom. It’s atomic number, or number of protons, the positively charged particles in an atom, and electrons, the negatively charged particles in an atom, is 30. Therefore, it has 30 protons, 30 electrons, and 35 neutrons, the neutrally charged particles in an atom. The atomic mass, which is found by adding the atomic number to the number of neutrons, is 65. Here is the computerized version of the format of the electrons: 2), 8), 18), 2). As you can see there are only 2 on the last ring of the atom so it wants to get rid of them and it is +2.===
