Which metal is resistant to all acids?

Gold
Silver
Platinium
Tantalum
Noble metals such as gold, pla­tini­um and pal­la­di­um can be dis­solved in aqua regia, a highly con­cen­trat­ed mixture of hy­drochlo­ric acid and nitric acid. Silver is soluble in pure nitric acid. Ruthe­ni­um can be dis­solved in aqua regia only when in the presence of oxygen, while rhodium must be in a fine pul­ver­ized form. Niobium and tantalum are re­sis­tant to all acids, in­clud­ing aqua regia.
