    1. The problem statement, all variables and given/known dat
    1. Why gold rings are not made from pure gold but mixed with other metals?
    2. Relevant equations

    3. The attempt at a solution
    my answer.....because when two elements are combined chemically they produce a new compound and this avoids particles from sliding...i don't feel it's appropriate...please help me out

    You should do some basic research on the properties of gold:

    Gold is only one metal, no other components, it creates electricity when contacting with other elements.

    Please elaborate. As stated this doesn't make much sense.

    Gold actually it's soft, so an 100% gold isn't practical, as it would change it's form. There is added some zinc or copper to make it more rigid.
    What I tried to say earlier it's that it could also react with some other elements, depends on conditions(in normal conditions gold dont really react), and having a gold ring with a bit of copper is much better then a gold ring with more active metals. For @saranya_sarah, if you still need.
    I hope it helped.
