We elaborate the uses of Zinc and atomic properties with characteristics. Zinc is a chemical element with a pale blue-gray appearance with atomic number 30. Its symbol is Zn and it belongs to the group of transition metals and its habitual state in nature is solid. Zinc is located at position 30 on the periodic table.
On this page you can discover the chemical properties of zinc and information about zinc and other elements on the periodic table such as cadmium, copper, gallium or scandium. You will also learn what zinc is for and learn about its uses through its properties associated with zinc such as its atomic number or the usual state in which zinc can be found.
You can see qualities of zinc such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in zinc atoms and other properties.
For some elements some of this information is unknown. In these cases we show the properties attributed to them.
Properties of zinc
Transition metals, also called transition elements is the group to which zinc belongs. In this group of chemical elements to which zinc belongs, there are those located in the central part of the periodic table, specifically in block d. Among the characteristics that zinc 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 zinc is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of zinc in its natural form is solid (diamagnetic). Zinc is a pale grayish blue chemical element and belongs to the group of transition metals. The atomic number of zinc is 30. The chemical symbol for zinc is Zn. The melting point of zinc is 692.68 degrees Kelvin or 420.53 degrees Celsius or degrees Celsius. The boiling point of zinc is 1180 degrees Kelvin or 907.85 degrees Celsius or degrees Celsius.
Zinc is a mineral that our body needs for its proper functioning and can be found in food. Through the following link, you can find a list of foods with zinc .
Uses of zinc
Zinc is a bluish-white to silver-gray colored metal. It is hard and brittle at most temperatures, but can be made malleable by heating to between 100 and 150 degrees Celsius. It is normally found with other base metals, such as copper and lead . The largest zinc deposits are found in Australia, Asia and the United States. Zinc is an essential mineral and is important to many aspects of human health. If you have ever wondered what zinc is for , here is a list of its possible uses:
- Zinc is mainly used as an anti-corrosive agent in metal products. It is used in the galvanizing process. Galvanization is the coating of other metals with iron or steel. About half of the zinc used worldwide is for galvanizing. Galvanization is used to make wire mesh, railings, suspension bridges, lamp posts, metal roofs, heat exchangers, and car bodies.
- Zinc is used as an anode in other metals, particularly metals used in electrical work or contact water of sea.
- It is also used for the anode in batteries. In zinc and carbon batteries, a sheet of this metal is used.
- Zinc is alloyed with copper to create brass. Brass is used for a wide variety of products such as pipes, instruments, communications equipment, tools, and water valves.
- It is also used in alloys with elements such as nickel, aluminum (for welding) and bronze.
- In some countries, such as the United States, zinc is used to make coins.
- Zinc is used with copper, magnesium, and aluminum in the automotive, electrical, and tool making industries.
- Zinc oxide is used as a white pigment in copier paints and inks.
- Zinc oxide is also used in rubber to protect it from UV radiation.
- Zinc chloride is used in wood as a fire retardant and to preserve it.
- Zinc sulfide is used as a luminescent paint for the surfaces of watches, X-rays, television screens, and glow-in-the-dark paints.
- It is also used in agricultural fungicides.
- Zinc is also used in dietary supplements. It is of great help in wound healing, reducing the duration and severity of colds and has antimicrobial properties that help alleviate the symptoms of gastroenteritis.
- It is also used in sunscreens. It is used in toothpastes to prevent bad breath and in shampoos to stop dandruff.
Atomic properties of zinc
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 zinc within the periodic table of the elements, zinc is in group 12 and period 4. Zinc has an atomic mass of 65,409 u.
The electronic configuration of zinc is [Ar] 3d104s2. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The average radius of zinc is 135 pm, its atomic radius or Bohr radius is 142 pm, its covalent radius is 131 pm, and its Van der Waals radius is 139 pm. Zinc has a total of 30 electrons whose distribution is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 18 electrons and in the fourth one, 2 electrons.
