Nickel properties
Transition metals, also called transition elements is the group to which nickel belongs. In this group of chemical elements to which nickel belongs, there are those located in the central part of the periodic table, specifically in block d. Among the characteristics that nickel has, as well as those of the rest of the transition metals, is that of including in its electronic configuration the d orbital, partially full of electrons. Properties of this type of metal, among which nickel is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The nickel state in its natural form is solid (ferromagnetic). Nickel is a glossy metallic chemical element and belongs to the group of transition metals. The atomic number of nickel is 28. The chemical symbol for nickel is Ni. The nickel melting point is 1728 degrees Kelvin or 1455.85 degrees Celsius or degrees Celsius. The boiling point of nickel is 2730 degrees Kelvin or 2457.85 degrees Celsius or degrees Celsius.
Nickel Uses
Nickel is a shiny silver-white metal with a slight golden hue. If you’ve ever wondered what nickel is for , here is a list of its possible uses:
- Nickel is used in many products. Some examples are electric guitar strings, magnets, and rechargeable batteries. Nickel’s magnetic properties actually make it a very important material for making computer hard drives.
- Nickel joins iron in an alloy to make stainless steel. Stainless steel has numerous applications. It is used in kitchen utensils, cutlery, tools, surgical instruments, firearm storage tanks, car headlights, jewelry, and watches.
- Various types of tin foil are made using nickel alloy with other metals. Nickel heat and electricity resistant alloys can also be made.
- Nickel is also added to superalloys. For example, mixing it with cobalt .
- Nickel is still used in many parts of the world for the manufacture of coins.
- Nickel is used to make alkaline batteries, as part of the electrodes.
- Nickel is used in a process known as a fire test. This process helps identify the types of compounds in a mineral, metal, or alloy. Nickel is capable of collecting all the elements of the platinum group in this process. It also partially collects gold .
- In chemistry, nickel is normally used as a catalyst for a hydrogenation reaction.
Nickel Atomic Properties
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find nickel within the periodic table of the elements, nickel is in group 10 and period 4. Nickel has an atomic mass of 58.71 u.
Nickel’s electronic configuration is [Ar] 3d84s2. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. Nickel’s mean radius is 135 pm, its atomic radius or Bohr radius is 149 pm, its covalent radius is 121 pm, and its Van der Waals radius is 163 pm.
