Which of the following metals do not react even with steam?

When metals react with water, they form metal hydroxides and hydrogen gas. 

Some of the metals react with cold water while some of the metals react with hot water. The copper metal does not react with steam because it is placed below hydrogen in the reactivity series and hence cannot displace H from hot water or steam.
$\mathrm{Cu}+{\mathrm{H}}_2\mathrm{O} \to \mathrm{No} \mathrm{reaction}$
