Nickel-Properties, History, and Applications
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal that is hard, ductile, and malleable. It is a transition metal and a member of the iron group, located in the middle of the periodic table.
Nickel has many important properties and uses. It is a highly corrosion-resistant metal that is used in many alloys, such as stainless steel, and in electroplating. It is also used in many other industrial applications, such as in batteries, magnets, and catalysts.
Some key properties of nickel include its high melting and boiling points, good ductility and toughness, and magnetic properties. It is also highly resistant to corrosion and oxidation, making it useful in many applications where resistance to wear and tear is important.
Nickel is an essential nutrient for many organisms, including humans, and is found in many foods. However, exposure to high levels of nickel can be toxic and may cause health problems such as skin irritation, lung damage, and cancer.
Nickel is typically obtained through mining and refining processes. It is found in many minerals, including pentlandite, garnierite, and millerite. The largest producers of nickel are currently Russia, Canada, and Australia.
Overall, nickel is an important and versatile metal that has many uses in industry and in our daily lives.

Nickel weight calculation formula
The weight of nickel can be calculated using the following formula:
Weight = Volume x Density
To use this formula, you need to know the volume and density of the nickel you are trying to calculate the weight of.
The density of nickel varies depending on its purity and form. For example, the density of pure nickel is about 8.9 grams per cubic centimeter (g/cm3), while the density of nickel alloy 625 is about 8.4 g/cm3.
To calculate the volume of a solid object, such as a nickel bar or coin, you can use the formula:
Volume = Length x Width x Height
Once you have the volume and density, you can use the formula above to calculate the weight of the nickel. Make sure to use consistent units for all the values (e.g. grams, cubic centimeters, etc.).
Here are some common products and items that are made from or contain nickel:
- Stainless steel (contains up to 18% nickel)
