Question

Silver and gold react with oxygen at high temperatures.
(A) True
(B) False

Answer 1

Silver is a white, soft, lustrous metal. It belongs to the period number $5$ of the periodic table. Gold is a bright yellow, lustrous metal. It belongs to the period number $6$ in the periodic table. Both of the metals occur naturally in elemental form. Both silver and gold are classified as transition metals.

Complete answer:
Silver and gold are solid at room temperature. Both are malleable, ductile, and conducting elements. They both belong to the group number $17$ . Silver has the molecular formula Ag as its Latin name is Argentum and gold has the molecular formula Au because of its Latin name Aurum. Both are classified as precious metals as they are rare metals and they have very high economic value.
The reactivity of metals usually depends upon how easily they lose electrons. This is usually determined by the reactivity series where elements are placed based upon their reactivity. The metals placed above are most reactive and the ones placed below are least reactive. In the reactivity series, silver and gold are placed below as they do not lose electrons more easily, hence they are least reactive. This is the reason why Ag and Au do not react with oxygen even at a higher temperature.
Therefore the above statement is false.
Hence the correct option is B.

Note:
Gold is not affected by air, water, alkalis, and all acids but aqua regia which is a mixture of $HCl$ and $HN{O_3}$ can easily dissolve gold. Both silver and gold are called noble metals as they are placed below the reactivity series.
