Buckle up, because we're about to dive into the 18 best nickel interesting facts that will surely leave you amazed.
Key Takeaways:
- Nickel is a versatile metal used in stainless steel, batteries, and even coins. It's essential for plants but can be harmful to humans in high concentrations, so it's important to handle it with care.
- Did you know that nickel was once thought to be worthless? It's actually a valuable element with unique properties, like resistance to heat and magnetic capabilities.
What is Nickel?
Nickel is a chemical element with the symbol Ni and atomic number 28. It's a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize its reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation).
-
Nickel was first isolated and classified as a chemical element by Axel Fredrik Cronstedt in 1751. Initially, he thought he had extracted copper but was surprised to find a new metal.
-
This element is primarily found in the Earth's core, which is rich in iron and nickel, making up a large part of the planet's composition.
Uses of Nickel
Nickel has various applications that make it an essential material in many industries.
-
About 68% of global nickel production is used in stainless steel manufacturing. Its resistance to corrosion makes it ideal for this purpose.
-
Nickel is also a key component in rechargeable batteries, including those used in electric vehicles (EVs), contributing to the green energy movement.
-
The metal is used in coinage; several countries have issued currency that includes nickel due to its durability and resistance to corrosion.
-
In addition, nickel finds applications in plating, where it adds a shiny, protective layer to other metals.
Nickel in the Environment
Nickel is not only valuable for its industrial uses but also plays a role in our natural environment.
-
Plants require small amounts of nickel to perform essential functions. It's a component of the enzyme urease, which is necessary for nitrogen metabolism in some plants.
-
However, high concentrations of nickel can be toxic to plants and animals, leading to environmental concerns in areas near nickel mining and processing facilities.
-
Nickel deposits are widely distributed around the world, with major reserves in Indonesia, the Philippines, Russia, and Canada.
Health Effects of Nickel
Exposure to nickel has both beneficial and harmful effects on human health.
-
Nickel is considered a micronutrient for humans, with a daily intake of about 25-35 micrograms considered necessary for good health.
-
On the flip side, prolonged exposure to nickel dust or compounds can lead to health issues, including skin allergies, asthma, and a higher risk of lung and nasal cancers.
-
Occupational exposure in industries that use nickel is a significant concern, leading to stringent safety and handling guidelines.
Interesting Nickel Facts
Nickel's unique properties and history are filled with intriguing tidbits.
-
A nickel coin in the United States contains only 25% nickel, with the rest being copper. This composition has been consistent since 1866.
-
The name "nickel" comes from the German word "kupfernickel," meaning "devil's copper" or "false copper," as miners once believed nickel was a worthless metal that contaminated copper ores.
-
Nickel has a melting point of 1455°C (2651°F) and a boiling point of 2913°C (5275°F), showcasing its high resistance to heat.
-
The world's largest nickel refinery is located in Norilsk, Russia, which is also one of the most polluted places on earth due to its heavy metal emissions.
-
Interestingly, nickel was used in armor plating during World War II, demonstrating its strength and durability.
-
Lastly, nickel's magnetic properties make it valuable in electronics and for magnetic shielding to block unwanted magnetic fields.
Nickel Nuggets: A Final Glance
