Which is the best metal to use in an alloy to increase its electrical conductivity? aluminum (al) silver (ag) zinc (zn) antimony (sb)

Among the given option, Silver (Ag) is the best metal to use in an alloy to increase its electrical conductivity.

Explanation:

Aluminium has a very high conductivity for electricity but the metal has very low tensile strength, alloy is made to harden it but that results in decreased conductivity. Silver has very high electrical conductivity.

When it is mixed with copper to form an alloy, becomes a very good conductor and a strong alloy for the electrical goods. Zinc has a very low electrical  conductivity. Antimony is a very strong metal but doesn’t have any electrical conductivity.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
