Creating an Efficient Electrical Cell to Optimal Chemical Combinations

[Jhenrique]

Which are all the possible combinations of chemical elements that a common people can use for manufacture an electrical cell that no needs of special care? (say me from better to worse, please)

Also, the combination Zn/Cu is the standard combination or is just a combination among several possible?

You can use any two metal where one metal is more reactive than the other.

Zn is more reactive than Cu.
As the reactivity difference increase,the voltage across the cell also increase

They don't even have to be metals, any two compounds that react spontaneously by a redox reaction will do, for example hydrogen peroxide + iodide ions. You can even make a concentration cell in which only the concentration of the reactant differs between the anode and cathode compartments: http://en.wikipedia.org/wiki/Concentration_cell .

Zn and Cu is the better option viable? If reactivity is the key parameter, so I could use K and Au...

I would like to provide a response to the content regarding creating an efficient electrical cell. First, it is important to note that there are many possible combinations of chemical elements that can be used to manufacture an electrical cell. However, the efficiency and effectiveness of these combinations will vary.

In terms of the best combinations, it is difficult to rank them from better to worse as it will depend on various factors such as the intended use of the electrical cell, the desired voltage and current output, and the availability and cost of the chemical elements. However, some commonly used and efficient combinations include Zinc/Manganese dioxide, Zinc/Carbon, and Lithium/Manganese dioxide.

It is also worth mentioning that the combination of Zinc/Copper (Zn/Cu) is a standard and commonly used combination in many commercial batteries. This is because it provides a good balance of cost, availability, and efficiency. However, it is not the only possible combination and may not be the most efficient for all applications.

In summary, there are many possible combinations of chemical elements that can be used to manufacture an electrical cell. The best combination will depend on the specific needs and requirements of the application, and it is important to consider all factors before determining the most optimal combination.
