With a Atomic number 30 it is a chemical element. • Zinc is a bluish-white, lustrous, diamagnetic metal •Zinc generates a characteristic sound when bent, similar to tin cry. • Humans have been using zinc for at least 1,100years. • Common reasons for use Corrosive resistant, Galvanization, batteries, acts as an anode, • Zinc disc attached to a ship’s iron rudder will slowly corrode alloys. • Zinc is a vital nutrient. It stimulates growth, fights infection and heals wounds. • Zinc is found in cells throughout the body. It is needed for the body’s defensive ( immune) system to properly work. Primarily in white blood cells. • Zinc is said to improve brain activity • People of high intelligence have high concentrations of Zinc and Copper in their hair. Those metals are essential for high brain activity such as faster connections between neurons and allowing electric transfers of nerves and neurons and smart people may discharge those metals via their hair. (Theory) • Zinc deficiency has been associated with major depressive disorder (MDD). • lost of vision with aging could be a sign of a zinc deficiency. • The America penny is about 90% and only 10% copper plated. • 24th most common element in the planet’s crust and yet Zinc is the fourth most common metal in use. • One study has shown zinc to be highly efficacious for curing warts. • The non-magnetic character of zinc and its lack of color in solution delayed discovery of its importance to biochemistry and nutrition. • The Importance to the human body was unknown until the early 20th century. • This sample is great for fun science experiments and element and metal Collections •This is high quality yet cheap affordable Zinc.

Palladium metal foil 99% pure element 46 pd chemistry sample
What you will receive •You will receive a 1.8ml glass vial of 99% pure palladium metal that is in a foil form. As seen in pictures. • Sweet Stocking stuffer, Christmas gift • Great chemistry gift •Amazing science gift •Teacher gift •Element collection The Facts •Palladium (atomic number 46) this sample is ideal for element collectors on the cheap or those conducting experiments. •Palladium is a rare, lustrous silver / white transition metal. (Platinum group metal) •Palladium is malleable and ductile and like gold, it can be beaten into thin leaf. •Palladium is remarkable in its capacity to absorb up to 900 times its own volume of hydrogen. As it absorbs the hydrogen, it expands visibly, like a sponge swelling up when absorbing water. •The largest use of palladium is in catalytic converters for automobiles. •Finely divided palladium is used as a catalyst for hydrogenation/dehydrogenation reactions and for petroleum cracking •Palladium is used in dentistry, watch making, and in making surgical instruments and electrical contacts. •It is also used to purify hydrogen because the gas easily diffuses through heated palladium. • This is high quality yet cheap affordable Palladium Safety / Caution • Keep out of reach from children! • Palladium is considered to be of low toxicity • Do not ingest • When working with metals it is a good idea to always have some type of eye protection, mouth protection and gloves on.
