Yes Silver and gold do not react with oxygen even at high temperatures as they are less reactive and are placed below the reactivity series. ... Gold isunaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) whichcan dissolve gold. Gold does reactwith halogens.

i asked why they don't react with hydrochloric acid but have written oxygen
Silver does not react with HCl. This is because, like other reactive metals, silver cannot displace hydrogen from HCl. Silver is below hydrogen in the reactivity series and thus cannot displace it. ... Well It reacts with HNO3(Nitric Acid) to give silver nitrate.
oh no need!
anyway thank you

according to the reactivity series of metals silver and gold are the least reactive metals after platinum and are highly stable. they are placed below hydrogen in the series. only those metals can react with hydrochloric acid that are placed above hydrogen like potassium sodium iron etc. therefore silver and gold do not react with HCl however hno3 and HCl combined in a ratio of 3:1 can corrode highly stable metals like gold due to highly corrosive nature.
