<div>SIR MY QUESTION IS THAT WHY SOME METALS DO NOT REACT EASILY SUCH AS GOLD AND SILVER BUT WE HAVE LEARNED THAT ATOM COMBINE SWITH EACH OTHER TO COMPLETE ITS OCTET AND WITHOUT THAT THEY ARE UNSTABLE SO THEY UNDERGO THESE REACTIONS BUT INSPITE OF THIS FACT WHY DO SOME &nbsp;METALS DO NOT READILY LOOSE ELECTRONS.</div>

Expert Answer

Chemically, gold and silver are transition metals and a group 11 element.

The transition metals become steadily less reactive and more noble in character from left to right across a row.

The relatively high ionization energies and electronegativities and relatively low enthalpies of hydration are all major factors in the noble character of metals such as gold, silver and platinum. Hence, they are highly unreactive.
